#6: Improves grammar

[taylon]

Hey @benjohnson @jpells @zacharytamas here is the first pull request for #6

It greatly improves the grammar:

• It doesn't break keyword arguments highlighting anymore
• "." are not highlighted anymore, to keep consistency with the python grammar
• Model fields, shortcut functions and settings were updated to sync with Django 1.8
• Added scripts to extract settings variables and shortcut functions from the Django source code, it will make it easier to update this package when new versions of Django are released.
• Scope names were updated to be consistent with other packages and scope naming conventions (http://manual.macromates.com/en/language_grammars#language_rules)
• Added highlighting for Form Fields

I also added keywords to the package.json file to improve package discovery (http://blog.atom.io/2015/03/30/keywords-on-atom-io.html)

Let me know if you guys have any suggestions to further improve this =D

Hey @zacharytamas

These scripts will never be executed or used by atom. The idea is to use them to update Django settings and shortcuts functions in the grammar when a new version comes out. They may not even be effective actually but I included them since I wrote it anyway to extract that from the source code.

Basically you would run the script, and it would generate something like this:

AutoField|BigIntegerField|BinaryField|BooleanField|CharField|CommaSeparatedIntegerField

Then you copy it into the grammar file.

Ah okay. I thought maybe you were training Atom to introspect settings.py files in project folders and learn their variables for highlighting/autocomplete purposes.
