Botpack repair button is broken on Windows

[VirxEC]

The botpack used to be in a \bots subdirectory, and so the repair button first clears the whole directory of its contents when pressed.

A recent change made it so the botpack is in the base RLBotv5 directory, causing the button to try to delete \bin, which fails because it contains the gui and server which are currently launched. When deleting the file fails, it exits having deleted the botpack but not redownloaded it.

Suggested fix: change the default install directory for the botpack back to its \bots subfolder.
