Add portable build to windows

[McGiverGim]

This adds a "portable" zip build to windows (win32 and win64) releases. In this way some of the complains about having different versions installed, or about problems with the installer will be gone.

It modifies the name of the "installer" to be similar to the portable one. The linux version adds the portable word too.

@McGiverGim Is this for 10.7.x only? Or do we get 32bit builds for 10.8.x now too?

We only build the 64 bit version. We can build the 32 bit version manually only.

@McGiverGim thats really cool.
One question - once we release or in nightly builds, are we going to have separate downloads for portable/installer or it will be one zip folder?

[McGiverGim]

Separate. One for installer, another for portable.
