Attempt to use symlinks to let demo and test html files work w/ common paths
fix permissions (remove execute)
move jquery-latest from src/third_party to demo/js

It isn't required by any brix so it doesn't belong in src
It seems that the path from base.js in the deps.js file can't use dot-dot (..) through a symlink.

I'm not 100% sure of this the results have been a little odd.
Ipc has moved from pearson.brix to pearson.brix.utils
Ipc has moved from namespace pearson.brix to pearson.brix.utils among other changes from the reorg.

These were the 1st files I was trying to get working.
They don't all work now. More work is needed.
