check_skip fixes (deepfakes#95)

* extended arguments for convert re deepfakes#85

* forgot to change helptext for extended arguments.

* Added -fr --frame-range argument to convert

accepts a list of frame ranges like `-fr 40-50 90-100`

still writes out frames that havent been converted.

* added --discard-frames argument

--discard-frames discards frames not included in --frame-range instead
of writing them out unchanged.

* Made training message slightly clearer

* Revert "Made training message slightly clearer"

This reverts commit 25a9744.

* Training status now '\r's rather than newlines.
Maybe its good, maybe its bad.
I like it.

* fixing deepfakes#90 (comment)

* Fixing issues with frame-range if no frame-range is specified.

* fixes for check_skip
