Contribute docsets to Dash

[Kapeli]

I've set up a repo where users can contribute docsets to Dash. You can check it out at https://github.com/Kapeli/Dash-User-Contributions. It should contain all the info you need to get started.

Docsets that are contributed in this way will appear in a separate User Contributed section under Dash's Preferences > Downloads (i.e. just like the current Ruby Gems or Cocoa Pods sections).

If you need any help with this, don't hesitate to contact me. Thank you!

Notes:

1. NumPy and SciPy are now "official" docsets maintained by me, there's no need to contribute them
2. iPython has been contributed by another user, but please check the docset he contributed and if you think yours is better, let me know

Thanks for notifying, will have a look at this in the next couple of days and take appropriate action
