Proposal 13059a - Branch Filtering - discussion of updates

Based on the stage 3 review from Eliot, it looks like there will be a few
changes to this proposal. At a minimum:

1. Remove the <noFileRenaming/> element that was proposed in stage 2, and
replace with 6 new elements suggested by Eliot. The 6 elements allow before
or after renaming (some.dita to either some-branch.dita or
branch-some.dita), and allow this style renaming for file names, keys in
the branch, and key scopes in the branch.

2. Remove the limitation that new branches cannot be created within
branches

I'd also like to have a short discussion about of some of the examples, and
about processing order related to this new feature.
