Added PlantUmlDiagrams package and PlantUmlConnection dependency

[evandrocoan]

I forked https://github.com/jvantuyl/sublime_diagram_plugin to https://github.com/evandrocoan/PlantUmlDiagrams adding a server dependency https://github.com/evandrocoan/PlantUmlConnection and rewrote the whole git history removing all the java binary files which have been added, reducing the repository size from 22.49 MB to 204 KB. So, now I cannot open a pull request to the original author because git points out:

jvantuyl:master and evandroforks:master are entirely different commit histories.

If @jvantuyl would like to receive such changes, he would have to override his master branch with mine. If he do not like that, I would like to add this as an another package under a new name. Otherwise I can close this pull request.

On this fork I already manually merged the pull request from @overlord pending for his repository:

1. #47 - support [png, svg, txt, utxt, latex] output image formats jvantuyl/sublime_diagram_plugin#59 support [png, svg, txt, utxt, latex] output image formats

I also fix jvantuyl/sublime_diagram_plugin#60 (Error Processing Diagram) the default example not compiling, also adding to output the error message from the Plantuml software.

This version now first attempts to contact the webserver accordingly to the new settings:

    // valid values:
    // 'png'              generate images using PNG format
    // 'svg'              generate images using SVG format
    // 'txt'              generate images with ASCII art
    // 'utxt'             generate images with ASCII art using Unicode characters
    // 'latex'            generate images using LaTeX/Tikz format
    // 'latex:nopreamble' generate images using LaTeX/Tikz format without preamble
    //
    // These formats are also supported by plantUml, but they need some
    // prerequisite to be installed... PlantUml return_code = 1 on invocation:
    // 'pdf' generate images using PDF format
    // 'vdx' generate images using VDX format
    // 'eps' generate images using EPS format
    "output_format": "png",

    // It will first try to use the server, because is much more faster than
    // calling directly the jar. If you would like to run a local server,
    // you can install it from: https://github.com/plantuml/plantuml-server
    "plantuml_server": "http://www.plantuml.com/plantuml/",

    // The full path to the plantuml.jar file
    "jar_file": "C:/Users/plantuml.jar",

@jvantuyl re-submitted their package in #6970. Can you guys fill me in on the current situation here?

[jvantuyl]

@FichteFoll Long story short, there was a hard fork because the two projects are really trying to do different things. Diagram aims to support any diagram-generating package we can include and has a plug-in architecture for that. It also is designed to be self-contained and not leak information to third parties in its default configuration.

PlantUmlDiagram is a hard fork. Rewriting the history to cut out bundled binaries has made merges impractical. It also has shifted to PlantUml only and many of the changes are slowly removing the plug-in architecture that was there. Finally, it requires an outside server to operate rather than bundling everything.

In terms of a feature comparison, Diagram vs PlantUmlDiagram:

• supports multiple viewers on different platforms vs more opinionated on viewers (which is less of a big deal with Sublime 3)
• has framework for multiple types of diagrams vs PlantUML only
• self contained vs requires upstream server
• runs disconnected vs requires internet connection (by default) / requires setting up a PlantUML server
• does not consume third-party resources by default vs does consume third-party resources by default
• bundles an often older-than-the-newest version vs gets newest version from third-party (by default)
• never sends any of your diagram code off of your machine vs sends your diagram code to third-parties by default

I really consider them to be separate products, with separate goals, optimized for different use cases. We share patches where convenient, but they're firmly diverged with firmly different feature sets. While there is significant overlap, I wouldn't say they're much worse than the overlap you find in some of the PEP8 linters and the like.

never sends any of your diagram code off of your machine vs sends your diagram code to third-parties by default

I got to remove that from my fork by changing the default server URL. Therefore, it will depend on the user adding the standard PlantUml server URL, or creating a local server and adding its URL or downloading the PlantUml jar and setting up the path to it on the settings file. On my computer, I have a local server running. I also recently added a feature to generate the diagram while the user type.

Thanks, @jvantuyl. That explanation was insanely useful.

[FichteFoll]

@evandrocoan could you fix the merge conflict, please?
