Move JS tests to test/javascript/tests
Goodbye Futon, old friend <3
Add Fauxton build process to Makefile

`make` alone now builds Fauxton along with the rest.

`make fauxton` to only do the fauxton build.

`make distclean` cleans the Fauxton build.

Fauxton is deployed into share/www. `make distclean` simply removes
share/www.

If share/www exists, `make [fauxton]` skips building Fauxton.

Includes a letter for Noah ;)
Add share/www to .gitignore
