Refactor subtitle options from srt to the more generic 'sub'.

Browse Source 
In order to be more consistent with different subtitle formats.
From:
* --write-srt to --write-sub
* --only-srt to --only-sub
* --all-srt to --all-subs
* --srt-lang to --sub-lang'

Refactored also all the mentions of srt for sub in all the source code.
