Created the folder js and moved minibar/support.js and minibar/pgf_online.js
there, to emphasize their status as app independent support libraries.
There are probably more files that should be moved here.
The cloud apps have been updated, externally hosted apps that link directly
to our server need to be updated too.
"gf -server" mode now contains everything needed to run the minibar and
the grammar editor (including example-based grammar writing).
The Setup.hs script installs the required files where gf -server can find them.
These files have been moved to a new directory: src/www.
The separate server program pgf-http is now obsolete.
