Add universal module definition support

-Add prepublish script and .npmignore so prod files are always present before publishing (not necessary now since prod files are in the repo, but would be necessary if prod files are not kept in source control)
-Add UMD task to add universal module definition boilerplate to main files (better support for AMD and CommonJS-like environments)

It seems to work fine with Browserify (excluding add-on validation modules) and with require.js.
However -- extra modules very likely won't work with Browserify out of the box. Users would have to transfer those files to the same directory the rest of the JS is in.
