Switch to git, new makedevenv script

[Chris]

I have switched the source code repository to git hosted on this web site, away from CVS at SourceForge. Gitweb for the repository is available at http://git.vomp.tv , the repositories can be cloned like this:

git clone http://git.vomp.tv/<projectname>.git

MartenR, who has worked on vomp for Windows and vomp for various other things, has a new vomp client git repository here which he will be using to experiment with a client for the Raspberry Pi.

I have updated the makedevenv script to version 9 to download the vomp client source code from the git repository.
