Minor cleanup of the cabal file.
Integrate JS driver code into server by means of QuasiQuotes. Same for a default HTML page.
Move examples into 'src' directory for easier testing and less code duplication. Cut down on extra libraries.
Rename cabal file and modules from 'Ji' to 'Threepenny".
More renaming, improve description in cabal file.

Tried to purge source code an comments of Ji and replace with rebranded Threepenny (or TP).  Some URL links still point to Chris's Ji stuff.  Note that even though I have changed the source of the examples, they do not build for me due to a build-depends issue already noted on github.
