Update to use base localisation
Merge pull request #169 from iain-benson/upstream

Update to use single storyboard and multiple strings files for localisation
Removed get-task-allow from entitlements as it was causing installation failures for non-jailbroken users, added German localisation thanks to @einfallstoll (pull request #168, fixes issue #78).
Enabled code-signing to fix Dropbox SDK support in the jailbroken distribution.
