Use -jsdebugger for build_and_run, and don't bind devtools on port 6100

Since -jsdebugger apparently works fine, there's no reason to connect to
Zotero from Firefox anymore. So just open the Browser Toolbox when
passing the -d flag to build_and_run, and stop having the devtools
server listen on port 6100 for devtools-enabled builds, since
-jsdebugger uses a random port of its own.
