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
