Deleting the updater/Unvanquished on Windows doesn't remove all registry entries

[VReaperV]

This results in updater failing after reinstalling (unless one manually presses the settings button at startup, which is not an intuitive solution to this issue) due to it still expecting daemon.exe to be there.

From another place:

Check HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Unvanquished Development\Unvanquished Updater
And HKEY_CURRENT_USER\Software\Unvanquished Development\Unvanquished Updater
Apparently HKEY_CURRENT_USER\SOFTWARE\Unvanquished Development\Unvanquished Updater might also contain some filediaglog stuff

These are apparently the entries not being cleared.

I'll take that as a vote for #109 and also somewhat #97.

Of course if you just delete stuff, rather than running an uninstaller, there is no possible way for the registry entries to be deleted.
