Restructure to normal python package

[simonvanderveldt]

As prepwork for publishing to pypi and to make it clearer/simpler to install and use.

Also fixed a bunch of PEP8/linting issues.
I only fixed the simple/non-invasive ones though, will have a look at the rest later.

How to use after these changes (see readme for more instructions):

$ pip install --user .

Partially fixes #11

[trentgill]

This all looks fantastic!

I wonder if it's easy / possible / worthwhile to add druid-upload and druid-download to the PATH as well? That said, I wonder if they are necessary at all. Does the ease of not needing to type u <filename> or p inside of druid surpass the potential confusion of having the separate python programs? I'm leaning toward just-one-tool-that-does-those-things.

CC @csboling before I merge these changes, wanted to check if you have opinions about this direction?

I'm super excited to just be able to type druid in terminal!!

[csboling]

Oh man, awesome. Clearly your pipcraft is stronger than mine. I've tried to get this kind of thing working for scripts many times in the past and have always had some variation I wasn't really happy with. I'm also super in favor of the namespace reorg to make local imports work as expected.

[simonvanderveldt]

Noticed we need to update the scripting tutorial if we merge these changes. Since the docs live in a different repo I'll create a PR there as well. Will do so tomorrow.

[trentgill]

I think we should also tag this release so we can tell people to download a certain version. another command-line arg would be good to query: eg: druid --v

[simonvanderveldt]

Yeah, good point. Shall we tag a first release when we've rolled the upload and download actions into druid (assuming everyone agrees with that approach)?
We can add a -v to report version to that release as well.

[trentgill]

sounds great to me. do you want me to have a go at the upload/download, or do you want to jump in (i won't be able to get to it til tomorrow earliest)

[simonvanderveldt]

I'll do it tomorrow, better to keep you free for other stuff :)

[csboling]

@simonvanderveldt I am getting an ImportError for find_namespace_packages on this line on Python 3.6.5 on an OSX VM. Not sure if this is maybe new in Python 3.7? Or maybe updating pip would fix it.

[simonvanderveldt]

Ohw, yeah, that's annoying, you need a newer setuptools. They should just include it in the Python package but alas.
So that either means adding more instructions or assuming people have setuptools installed and switching to using find_packages and including __init__.py files.

[simonvanderveldt]

I've updated the readme to include updating setuptools and I've removed the virtualenv section, users should just use pip install --user, people that want to develop/work on it I assume know what they're doing and even if we want to document it for them it should be in a separate readme.

[simonvanderveldt]

I've added a PR to update the docs as well monome/docs#142, I think this is all ready.

[trentgill]

Merged! I'll add the changes to scripting.md now to cover bowery.
