Usability Updates

[mnadareski]

This PR is a combination cleanup and feature update, including some WIP items that are not hooked up.

Starts the framework for the following:

• Checking drive speed without the need for DIC (Drive speed finding (without DIC?) #69)
  • There are a couple different prototypes for this currently, there's no guarantee that either of them will be the ultimate solution
• Report if a disc is XDG3 (Report if an X360 disc has XGD3 #71) - this is by virtue of the next item

Adds the following abilities:

• Detecting disc type automatically (fixes Detect Disc Type Button #49) - this is not 100% complete as DVD-based discs will show up as DVD only (XBOX/360 discs especially)
