Documentation of the Configuration Options

[Sebastian Huber]

Hello,

I added the configuration groups and options as specification items:

https://git.rtems.org/sebh/rtems-qual.git/tree/spec/acfg/opt

I can generate the latest documentation sources one-to-one from the 
specification with this module:

https://git.rtems.org/sebh/rtems-qual.git/tree/rtemsqual/applconfig.py

My next step is to introduce the new templates:
