Tested using a WinXPsp3 virtual machine:
- Installed bitcoin-0.4.5rc1-win32
- Installed bitcoin-0.6.0rc4 on top, ran bitcoin-qt
- Uninstalled bitcoin-0.6.0rc4
RESULT: bitcoin.exe left in C:\Program Files\Bitcoin
This pull will clean that up. HOWEVER:
RESULT: locale\ folder left in C:\Program Files\Bitcoin
Is Qt writing that folder at first startup? I don't see it mentioned in the setup.nsi; should the uninstaller explicitly remove it?
