n900-encode.py - Version 1.2

And here is the next version of my n900-encode.py script. Notable new features are CRF-Encoding as an addition to average bitrate encoding and some tweaks for N9 friendly videos, since I have a N9 now (no worries, the videos still work fine on the N900). The CRF-Encoding is turned on by using a video bitrate below 52, which is then interpreted as the CRF-Factor. The default setting is now CRF with a factor of 22. Also the usage of styled (SSA/ASS) subtitles is now turned on by default. As usual get it from my GitHub page and let me know what you think about it in the comments below.
