Enhancements to script installs

[Chris7]

These are some ideas for enhancing script installations. Some are impractical and too bloated, but if we can figure out a nice, clean easy way to do it eventually it may be worth it:

• The ability to install a package with pip. This would add a package to a new model that is checked and run on wooey startup. For the first run, scripts will be parsed from the setup.py and installed.
• Use digests to determine if we should update a script. Instead of tracking with versions, we track a digest.
• Install a script from a url/gist/etc.
• A console to write/save scripts in for eventual integration to Wooey. We can run these scripts as jobs so users can test output/etc.
• Add support for bulk-importing multiple scripts (optionally from a remote URL). The use-case I'm thinking would be to have repositories ("BioWoo" etc.) containing bundles of useful-for-everyone scripts that new installations can import.

I was wondering about supporting a shorthand way to install certain "libraries" of scripts that we could recommend/include. The implementation would be simply distributing a file containing shorthand names (e.g. bio, chem, biocode etc.) linked to URLs to install them. Then the command line would be simply:

python manage.py addscript #biocode

...or similar. Some kind of prefix marker would be required to avoid filesystem clashes or this could be put under an alternate command for example:

python manage.py addlibrary biocode

We could adopt the + nomenclature pip uses like git+url. We can do addscript pip+biocode or git+url, etc.
