[OpenMatt]

Add these toolbar buttons to the "GitDone" browser extension

[OpenMatt]

For 0.1 release:

These buttons will be simple bookmarks only. To keep it simple and reduce scope.

• New task goes here: https://github.com/OpenMatt/GitDone/issues/new
• New project goes here: https://github.com/new
• Notifications goes here: https://github.com/notifications?all=1
• My projects goes here: https://github.com/OpenMatt?tab=repositories

Out of scope / pushed to 0.2:

• Clone task

How about using Octicons? They are already loaded and available. https://octicons.github.com/

Doh, that's genius. :-)

Moving this to 0.3 0.2 can just be about making it easy for other project managers to install.
