Mash should support registering BSAs

[Yacoby]

Since you can install mods with BSA files included in BAIN I think it could be convenient for anyone if BSAReg.exe (free to distribute) and perhaps GetMWRoot.exe (perhaps permission is needed) as well was included in WMSA, so that you can launch each program from the utilities tab if you want that.

To be honest I'm partial to having some of the custom functionality from all the various command line programs simply added to the menu or instructions on how to add this to the Utils tab.
