Alfred 2.4 Build 279

What's new in this version:

Compatibility Improvements:
- OS X Yosemite Compatibility, Alfred 2 officially supports Apple's upcoming operating system
- Updated Alfred preferences framework to provide a unified synced / non synced preference codebase for Alfred, giving better reliability

Theming Improvements:

- Sharper status bar icon which respects Yosemite theming
- Add the experimental default window blur into appearance > options, no longer a preferences hack
- Add Helvetica Neue and Helvetica Neue Light to Alfred's theme editor selection
- Don't sync window position as different Macs may have very different location requirements
- Fix quirky footer text in theme editor when cycling through options such as fonts

- Update the "Show Result Subtext" appearance settings and add in a few nice new options such as only show subtext for selected row, or only show for alternative (modifier) actions
- Add a 'show subtext' modifier option in Alfred's advanced preferences. This allows to peak at the default subtext, e.g. file path, if the subtext is hidden in the theme
