[mythtv] Minor typo in the docs

[Tom Panning]

In the howto section 1, it says:

NOTE: If you are going to use CVS to compile MythTV rather than using the 
distribution tarball, it is strongly recommended that you join the mythtv-dev 
mailing list.

The link on the word "join" points to the subscription for mythtv-commit, but 
it should point to: http://www.snowman.net/mailman/listinfo/mythtv-dev/

Just thought you would like to know,
Tom

By the way, I'm loving MythTV. Now I just need to get a faster computer with a 
larger hard drive...
