Updated target api level to 19
Fixed NullPointerException that crashes the app under some circumstances. I cannot seem to replicate the NPE to determine the underlying cause so for now the error will be suppressed. The crash occurred because mMediaServer was null in BrowseFragment (and hence DirectoryLoader where the NPE occurs). The other loaders have been updated to check for a null MediaServer.
Sorting directories is now done case insensitively
Restored the "remove from playlist" context menu item
Updated loop/repeat logic
Removed "experimental" label from DVD navigation UI
Updated Spanish translations
Fixed homescreen widget size
