[Cin] Add 16:10 aspect ratio to dropdown menu in format window?

[Andrew Randrianasulu]

Hello, I was screencapturing lately, and of course was confused *again* by my monitor being 1440x900 (16:10) vs 1920x1080 being 16:9 ..Of course I corrected myself, yet black bars remain ...

I re-encode into 1080p for Youtube, because otherwise it really blurry :(

you see, there is black area around actual image ... When I *finally* realized I must manually enter aspect ratio 16:10, some of those bars disappeared ....

Sorry for not testing CinGG much - I have new toy:

(no, ffmpeg's openCL still doesn't work with this)
