Fix bash arg quoting, remove bash/batch shortcuts on uninstall

Put quotes around the args passed to the bash shell script (without quotes spaces in the args will not work)

When a Chocolatey-Uninstall is done, the bash and batch shortcuts will now be removed using Remove-BinFile

I've also added a message in Generate-BinFile that the bash shortcut is getting added, as this was missing.

I've also added a message to Chocolatey-Uninstall describing which directory is removed on uninstall.
