Update README
Add relevant contents of doc to README

Since this tool is now just vCloud Launcher, there is no need for the documentation to be in a separate directory rather than in the README. While moving it over I also corrected some things that are now out of date and clarified others.
Move Launcher files to their own directory

This only moves the lib files, not the spec files, so as not to make this commit too complex. All tests still pass at this point.
Move tests to launcher directory
These are for tests in vCloud Core

So are not required here. Deleting rather than removing from history for clarify, as they've been hanging around in vCloud Tools for some time.
