Using VERSION to determine the MisterHouse program version.

I propose to use the VERSION file in the root of the MisterHouse codebase to determine what version of Misterhouse we're running.
This is opposed to the hardcoded version in bin/mh.

I've cleaned out some legacy code that tried to determine the svn version (we're no longer using that) and now bin/mh reads the VERSION file. For the master branch this file reads 'unstable' by default. When we make a new version now, we only need to update the version number in the VERSION file to have it pushed to all locations in mh that rely on or use the version number.

Fix Issue #132: Remove tracking scripts from user docs

docs/toc.html contained two tracking scripts which no one on the project recalls.  Scripts have been removed and can be added back in later if someone comes up with a patch that supports opt-in.  The way the docs directory works every local MH copy was running the scripts as was the toc.html on sourceforge.net.
