android: Drop custom file abstraction + UI

Android Viewer had its own file abstraction layer.

From the (now deleted) IFile.java:

> An abstraction of the File class, intended to be implemented by different
> Document Providers.
>
> It represents a file or a directory in the context of a certain Document
> Provider. It wraps the file-related operations and provides access to the
> final document as a local File, downloading it if necessary.

However, Android already provides such an abstraction by
what is called "documents provider" there as well, s. [1].
Android Viewer has previously been adapted to
support and make use of that.
Therefore, drop the custom implementation to avoid
duplication and having to reimplement functionality
already provided otherwise.

Also, drop the custom UI elements to display and
select files implemented on top of the custom
file abstraction. Support for using the system file
picker (via the corresponding Intents) has been added
earlier and is now the only available option to open
files from within the app.
