Hopefully fix PendingIntent.getActivities() documentation wtf.

The first intent is the key. No wait, last! Or was it first?

I haven't actually read the code, didn't write it, and haven't tested
its behaviour, but surely it can't be both, and last is the only one
that makes sense.

Correcting typo in doc of MEDIA_XXX intents

Correcting typo in documents of MEDIA_MOUNTED,
MEDIA_UNMOUNTED,MEDIA_UNMOUNTABLE intents, which
may be confusing to APP developers.
