BundleInstall failed if 'shellslash' is set on Windows.

I think vundle should consider this scenario.

There are some old issues which look similar: #111, #170, #374, #380. You can look there for a temporary fix. Please also try to manually update Vundle from the command line.

If the problem exists with the newest version of Vundle, can you please give a minimal vimrc file and a short list of steps to reproduce (and find and fix) this bug.

@starcraftman can you have a look at this please?
