Simplifies command-running with spawn
Ignore compiled JS

Note - I might add this back in later, to allow people to grab the file from
Github. But probably not.
Removing some cruft

These may be added again in the future, but for now, I want to focus on the
browser tests.
Package cleanup

The start command no longer exists.
Minor README fix

mentions an optional command
Gets the mocha tests running in the browser.

Run `cake test:server`, and follow the instructions. The libs had to be
modified to work equally well in the browser and in NodeJS, and fpcalc needed
to be kept out completely (by returning unless a global `require` function is
available). That's OK, though, because it won't be run in the browser, but the
other modules will, and they're all passing.
