Restructure the repo

[jalovatt]

The existing structure is starting to get a bit messy now that I've added the test library.

Suggested:

    --library
        --gui
        --public
        scythe.lua
        set-scythe-path.lua
    --development
        --docs
        --examples
        --templates?
        --testing

• Can a ReaPack install from the ReaTeam repo grab files directly from here? It would be simpler if only the metafiles had to be pasted and updated.
  • Problem: Releases would need to be tagged here as well so ReaPack could link to version X consistently rather than always downloading from Master, which would have users downloading changes that aren't reflected in the ReaPack info.
• Should the separate library + development packages be kept, or just distribute them all together?
  • The library is currently 200kb with another 50kb for the dev stuff, so size is probably not a concern
  • Would mean an update for all users whenever dev stuff is updated
• Where should the tests live? With their modules in a subfolder, or all of them under development/testing?
• The test library would need to add its own path to package.path, I think.

Partially done - the library has been restructured, and the development path is exposed for require when necessary.
