Initiate re-index from Android client

[Subsonic_User]

Not sure how popular this feature would be but would personally be a "nice to have". It would be nice to be able to initiate a re-index from the Android client. I currently have it scheduled to rescan every morning but when I add music I'll either have to log into the web gui (which frankly I never really use) or just wait for the re-index.

The other option that would accomplish the same thing would be to have subsonic monitor the folder for changes and automatically recreate the index but I imagine that would be a lot more difficult.
