Fetch the issue properly by its internal id instead of its external id, making the routing work properly

Make retrofit callbacks better by simplifiing them so that all errors are handled in the onAllError block.

Reload issues when open/close issues. Also, remove reassign dialog in favor of going into the edit screen

Merge request activity. Form validation for URL during login. Improve timestamp from dates. Swap order of issue comments to match web. Update support libs.

Update plugin. Make it where issue id title uses the internal id. Allow user to control if they are viewing open or closed issues, and allow user to control if they are viewing open, merged, closed, or all merge requests. Add activity transition between list of groups and group detail.

Update to latest support libraries, improve the dialog themes, fix issue with double share intent, and do a whole lot of improvements with Issues.
