Beta v0.1

This is the initial beta release of MCC Mod Manager. I am releasing this under Beta because I know that there are a handful of improvements that I can make before the official v1.0 release. These are mostly quality of life improvements (like adding a progress bar) and additional error checking to avoid odd edge cases. As far as I know, there are no major issues with this current build. Any bugs or improvement suggestions can be directed to the Github Issues page here.
