updated url for windows installation

Hi, I've changed url for windows installer because I was getting an error when trying to clone via git: protocol:

E:\Documents and Settings\Tobii>git clone git://github.com/tanepiper/SublimeText
-Nodejs.git "%APPDATA%\Sublime Text 2\Packages\Nodejs"
Cloning into 'E:\Documents and Settings\XXX\Application Data\Sublime Text 2\Pa
ckages\Nodejs'...
fatal: unable to connect to github.com:
github.com[0: 204.232.175.90]: errno=No such file or directory
