DOC: Add some notes for using on Fedora 22.

[charris]

Getting numpy-vendor working on Fedora 22.

[juliantaylor]

you could just use virtualbox on fedora, should be simpler

[charris]

Yes, and my natural aversion to virtualbox and needing to get it from Oracle kicked in. In any case, I think libvirt is the default for modern (as opposed to Debian ;) versions of vagrant.

I did run into a problem with Python 3.4, the old missing vcvarsall.bat problem. Not sure how to fix that.

Okay, this can't hurt so in it goes. Thanks @charris.
