 cli/scripts Refactor (#367)

* Refactor for PEP 8 and split process function

* Remove backwards compatibility for skip frames

* Split optional functions into own class. Make functions more modular

* Conform scripts folder to PEP 8

* train.py - Fix write image bug. Make more modular

* extract.py - Make more modular, Put optional actions into own class

* cli.py - start PEP 8

* cli,py - Pep 8. Refactor and make modular. Bugfixes

* 1st round refactor. Completely untested and probably broken.

* convert.py: Extract alignments from frames if they don't exist

* BugFix: SkipExisting broken since face name refactor

* Extract.py tested

* Minor formatting

* convert.py + train.py amended not tested

* train.py - Semi-fix for hang on reaching target iteration. Now quits on preview mode
Make tensorflow / system warning less verbose

* 2nd pass refactor. Semi tested

bugfixes

* Remove obsolete code. imread/write to Utils

* rename inout.py to fsmedia.py

* Final bugfixes 
lib/cli.py
