ffx264 & ffhevc for Linux/BSD

[microchip8]

I wrote two small, simple and basic shell scripts for Linux. I did it because I encountered a few video remuxes (from my own Blu-rays) that I couldn't encode with my h264enc script so I turned to ffmpeg which was able to handle them.

ffhevc & ffx264 won't be anything big and professional like h264enc. I intend to keep them both basic and with the options I most often use so stuff like many audio/video filters, different input sources, etc, etc won't be added, unless I really need them on a frequent basis in the future.

However, if you need something and are willing to implement it, I accept patches.
