v1.2 - Implementing Fork Improvements

Notable changes with Fork

GUI redesign

• Easier input of time start with some more back end work to allow lazy input. (can ignore colons and avoid entering in a verbose start time like 00:00:00
• Easier input of file paths: you can now just paste in the paths into the text fields, or click the button all the same.
• You will now be warned if the given width does not coordinate with a 16:9 ratio to avoid scaling artifacts

"Ultra" quality has been renamed to "Iterate" - to better indicate that it will iterate on multiple ffmpeg runs

• I've also reduced the maximum amount of runs to five, and doubled the decrement in bitrate so the same end result will be met as before, but in half the iterations.
