Okay, so I may have gotten carried away with the improvements. Here's what's new:
The actual MCS is now displayed in each frame. The movie maker reads the MCS from the screenshot's name to assume the MCS. (As a fallback, it assumes screenshots were taken every 1 MCS). Resolves #41.
Fixed delay in movies. Previously, the first 2 seconds gave a black screen. (#41)
Added a checkbox to make MCS text on movies optional
Added button to show the movie directory in file explorer so that it's easy to find newly-generated movies.
