Campaign to Save the CLI

[thw26]

Fixes #128. Requires #158.

I should clarify my aim is to get it working and to make it pretty later (cf. #172).

Part of my goal in this PR is to make #147 potentially easier. The CLI is intentionally aiming to be a highly simplified event/queue manager, thus I aim to clear the event's status frequently in order to reuse it later. The TUI is, to my knowledge, never waiting on more than one event at a time. Therefore we have not need to have multiple events. If we do have some place where we are waiting on multiple, then we can have two different ones at that time. This would make the code much simpler, leaner, and easier to reuse.

What I imagine therefore, from this PR, is extracting all the event/queue code from the TUI, the CLI, and the GUI, into its own class module.

This is fixed in #182

heavy_wineserver_wait() was only being used after running winetricks commands, and after adding debug logging there don't seem to be any processes still using the WINEPREFIX when winetricks commands finish and wineserver_wait() is run. I suggest we keep the debug logging for the time being, that way if anyone has problems b/c of no longer using heavy_wineserver_wait() we'll be able to see if it's due to the WINEPREFIX still being accessed by something.
