Issues/#30 commands help

[barthanssens]

This PR addresses GitHub issue: #30 .

Briefly describe the changes proposed in this PR:

• Move command line parsing to new class CmdLineParser (reducing the lines of code in Console class)
• Move commands to separate (sub)package to make a better distinction
• Move short description and help text to the commands (instead of a separate PrintHelp file with constants)
• Let all commands inherit from new ConsoleCommand class (which implements the old Command interface + new Help interface)
  • This also includes the QueryEvaluator (with two new small sparql and serql classes, making them "normal" commands as well, instead of special cases)
• Order commands alphabetically

I've rebased this to the develop branch and scheduled it for 2.4.0 release. Let me know if that works for you Bart.

[barthanssens]

Thanks James, works for me :-)
I'll use the 2.4 dev branch for the other things I'm working on (#21 and #43)

Looks a lot cleaner, good stuff. There's code formatting issues though. IIRC @barthanssens you are not using Eclipse IDE, correct? It might be worth looking at how to port our Eclipse code formatting settings to your IDE, could also be useful for other RDF4J devs that use a different IDE.

[abrokenjester]

Looks like a code formatting issue. @barthanssens can you check your indent settings (or if you're using Eclipse, make sure the project is set to use the predefined RDF4J code formatting settings?). Looks to me like it adds a second tab in a conditional block.

More generally it might be good for a dev who uses eclipse to run reformatting on this PR.

[barthanssens]

Thanks, I'll fix the formatting issues
(and indeed, I'm currently using NetBeans instead of Eclipse, probably forgot to run the formatter / activate the Eclipse formatting rules)
