Android Kitkat Fallback

Android kitkat doesn't support file uploads unless they come directly from another app or the camera. Making that logic work however is not among the easiest and surely not the cleanest of jobs.

I've written some logic in the project to determine if the user is on a kitkat (android 4) or below device. If so the default message plus an optional dictAndroidFallbackText is shown (that can be set from the settings like other dict-options).
