Gallery2: Modify AOSP EL translations

PS1: Modify the AOSP image size translations like I did in all previous android
versions, the current greek translation does not sound right and it's not used
in any other products (cameras, etc.) in it's current form.

PS2: Update title

PS3: Fix wrong gender in plurals

Gallery2: fix HDR crashes && fix exposure from being set.

* HDR transcoding is done on a different thread. got rid of the
stall in the transcooding step and possibliy fix race conditions.
* lock out the exposure step from being set, also fix an issue
of setting is being set by a method that is called on idle.
