Install Game (1:1) only works once after scrubbing

[594rk]

Without closing the manager or changing the directories.
First, select one or more games and run "Install Game (Scrub)"
Second, select two or more games and run "Install Game (1:1)" .

During that second run, the first (1:1) game will install as intended, but all others in the queue will be scrubbed instead.
The manager will then crash after its finished with the queue.

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Fix in the works, completely rewrote scrub loop, was stupidly overly complex.. which was a lot my fault.

K.I.S.S. ... So that's what I did./am finishing up.

Got a little sidetracked with the rewrite because I'd like to be able to actually make use of the config menu and the different .. formats/transfer systems. Especially for in the future. Also noticed some inconsistencies when it was skipping around behind the scenes (way too complex, steps got skipped accidentally sometimes because while laying out the 'do this after' part (adding an event to process.onExit) actually just spawned a new thread that ran that code live instead of storing an event to be used later.

I'm still wanting to add WIT and replace GCIT.. but not yet.
