Include all relevant licenses and fix license formatting
This adds all of the licenses from CMFM, specifically its two libraries.  Also added HTML <br/> tags to conform to the original formatting of each license.
Replace old CM icons with the new Backbone icon
We can make activity specific versions of the new icon later, but for now we should only be using that new icon.
Hide theme preferences
Since we don't actually use themes at this point.
Add preference header icons
This commit is unavoidably hacky because Android won't recognize header icons defined via theme (?attr/xxx), so we have to do it programmatically.  We're only dealing with five headers in all, so I'm ok with how this had to be done.
Capitalize dashclock extension action bar title
The action bar title for every other extension was capitalized, so it would be best to conform.
Give dashclock preference header its own string
So that it isn't sharing it with the Dashclock initiated instance of the preference.  Each instance needs to adhere to different a different 'context', so they need different titles.
Preference string cleanup
Load correct Dashclock settings home icon
Based on whether the preferences activity was opened from Backbone or from Dashclock
Merge pull request #71 from bkensey/dev-settings-cleanup

Reviewed & tested! Looks good! We may want to update the Dashclock pref icon, but that can come later.
