version control symlinks.

I'm not sure if this will work on windows, but it's good on linux (and
presumably OS X). If tracking symlinks work, it should eliminate the need for
setenvironment.sh.

I'm leaving setenvironment.sh in because I don't know if this will work on
windows and because I don't understand why firefox needs hardlinks for
localizations.js and core/utils.js.

better setenvironment.sh

it's now platform-independent (works on linux) and doesn't use symlinks for the
chrome dir (so loading an unpacked extension works for debugging).

The /new/text page is ajax now, meaning you can't just wait for document.ready,
you have to poll for the form's creation.
