User interface changes:
- Fixed bug on some systems where the tag field would not show all tags or any of the colors.
- Fixed clicking on tags in the dropdown making the dropdown disappear (and not adding the tag to the field).
- Fixed duplicate entries in the tag list.
- Made color label picker resemble the newer round tag look on Mavericks systems.
- On Mavericks systems, the color label picker should now show the proper tag names associated with the color when you hover over the color chits.
- Fixed color label action not working for some people on Mavericks.
- Setting the color on a file will now set all tags of that color on the file, and not whichever one it finds first.
- Helper process should switch back to the integrated GPU instead of staying in discrete GPU mode.
- Various fixes.
