Added qdoc conf & source files for each
StatusQ module. Documented StatusBaseText
from StatusQ.Core as an example
To generate docs, from sandbox/docs run
/path/to/Qt/installation/bin/qdoc statusq.qdocconf
A folder named "html" will be generated under sandbox/doc,
open the statusq-index.html to get to the home page.
Closes#550
