UI: Set 8x8 as minimum selectable resolution

Browse source 
Since libobs internally rounds to various powers of 2 to support SSE
functions, resolutions that are too low can get rounded to zero. libobs
will fail to startup with a zero resolution, so if a user accidentally
entered anything that rounded to zero OBS would become unusable without
manual fixing by editing the profile .ini.
