Merge branch 'develop' of github.com:frakbot/FWeather into develop
Fixed a couple of user-reported bugs

- Crashing on 2.3 when opening the Authors dialog (was a SherlockFragmentActivity, shouldn't have been)
- Crashing when GPS is the only available location provider (missing permission)
Default update frequency set to 1 hour (was 5 min)
Updated preference keys constants
Made FLog actually useful.

Still not run once, will test after implementing the Debug setting UI.
Added the Debug setting
Set DEBUG default to false

Also set fixed text color in About dialog to avoid low contrast issues on strange OEM custom UIs (such as Moto's)
Updated the changelog, ready for 1.1-beta2
Bump version to 1.1-beta2
Fix for about text color (duh!)
WIP fixing logging stuff.

Still to fix log happening even when log level shouldn't allow it.
Fixed logging (not trying to use setprop anymore)

Resorted to a bypass mechanism for the FLog setLogLevel functionality, cause System#setProperty is useless, shell's setprop isn't callable by apps, and I don't want to rely on reflection on SystemProperties (not even sure it would work!).

A few refactorings and minor fixes here and there.
