Adds converter modules and sorters

Converters are now the result of combining multiple modules, and running them in the selected sequence. I hope to be able to completely remove converters by replacing them with templates that simply run some modules in a sequence, before running FFmpeg. Then I want to be able to parse a command into a template, so users have full control of what a template does.

Sorters each sort a list of streams after a single criteria. They can be chained in order to create complex chained sorters.
