review at your discretion :), in particular:

 - update_all.sh and update_from_log.dart are the new additions here.
 - edit_buffer is a copy of code that we have reviewed too many times, it should
be in its own package, for now I'm just cloning it
 - record and log_parser I have been using in my bot_failures package. Coping it
here since that package is now obsolete




Bob - this is just FYI for you about the .status file location. There is a TODO
in update_from_log.dart where the corelib_2.status file is hardcoded.

thanks, as discussed I deleted editbuffer and now I'm just replacing a string in
one go.
