docs beat format

[Jens Petersen <petersen redhat com>]

Hi,

I was trying to clean up the docs beat hierarchy a little so that the the contents list looks right.

What should the default toplevel header be in a docs beat page?  I mean level 1 ("= Beat Title =") or level 2 ("== Beat Title ==")?  It looks to me like it should probably be "==" but some pages are using "=".

It would be nice to make it consistent to make it easy to browse the docs beats page and encourage more people to contribute.

Thanks,
Jens
