Subject: Open org-protocol:// links on Android

* doc/emacs/android.texi (Android Startup): Revise to reflect
changes in the set of files registered for Emacsclient and
mention org-protocol support.

* java/AndroidManifest.xml.in: Open all files, not just a
particular subset of image and data files.  Register an
org-protocol scheme handler.

* java/org/gnu/emacs/EmacsOpenActivity.java (onCreate): Provide
URI to Emacs verbatim if its scheme is `org-protocol'.
