ref-manual: Downplayed the BBLAYERS_NON_REMOVABLE variable. 

Applied some suggestions from Paul Eggleton to downplay the role
of this variable.  It is basically ignored now in all parts of the
manual set except for the descriptions of the variable itself
and the BBLAYERS variable.  I added some text reinforcing the fact
that BBLAYERS_NON_REMOVABLE is ignored by the build system and only
matters if you are using Hob.
