Keep https://dist.torproject.org/win32/ up to date

A user reports finding the most recent tor binaries for Windows in https://dist.torproject.org/torbrowser/5.5a3/tor-win32-0.2.7.2-alpha.zip

In https://dist.torproject.org/win32/ , the latest version is 0.2.4.23.

Can we:

• make sure any compiled versions of Tor for Windows end up in https://dist.torproject.org/win32/
• Remove old versions from https://dist.torproject.org/win32/
