[TIMOB-3448] Android: cannot retrieve EXTRA_STREAM from Intent (no getUriExtra)

I'm using Titanium Mobile 1.5/1.6's support for native Android intents and activities to let our StatusNet Mobile app accept text and image attachments from other social networking apps and the system Gallery and Camera apps.

Unfortunately I'm having some trouble accepting images, which are attached as a Uri object in the EXTRA_STREAM extra field. Calling intent.getStringExtra(Ti.Android.EXTRA_STREAM) fails, because the returned object is a Uri, not a string:

W/Bundle  ( 1569): Key android.intent.extra.STREAM expected String but value was a android.net.Uri$HierarchicalUri.  The default value <null> was returned.

I notice in ticket #2587, someone encountered the same problem when creating such intents to send to other applications, and an Intent.putUriExtra() was added to accommodate it, converting from a string parameter to a Uri.

It looks like it would be helpful to add an Intent.getUriExtra(), or else tweak things such that there's some other clear way to retrieve it.
