Colorcoder now allows saving to custom directory locations

Modified Colorcoder to allow saving custom (Colorcoded) color schemes to custom directory locations.

I also added a custom max_size so people who have beefier machines can have it automatically turn on for larger files.

[sublime API](http://www.sublimetext.com/docs/3/api_reference.html#sublime.Settings) states:
>`get(name, default)` Returns the named setting, or default if it's not defined.

what you are doing here is essentially

     set.get('max_size',set.get('max_size'))

which is redundant
please revert this and following changes of same manner
