update IntelliJ proj file for 12.1.6 on Grails 1.3.9 on Linux
initial grails 2.3.4 upgrade (without running)
updated conf files from a fresh 2.3.4 proj.

merged a few lines of the old Config & BuildConfig, but mostly replaced.  (not run yet)
added wrapper files from a fresh 2.3.4 proj.

not planning to use, but just so they are available for conventional use by others if wanted
added size to Person.photo and changed Settings.dateFormat to String.

This enabled run-app to start the app (i.e., get past BootStrap).
copied error.gsp and layouts/main.gsp from a fresh 2.3.4 proj.

Merged some lines from the old main.gsp.  The new error.gsp provides more helpful stack trace source code context.
specify prototype instead of jquery.

2.3.4 has a different default js lib.
moved prototype require to head of main layout.

That is a slow place for it, but it must be there because the old application.js depends on it.  (todo: convert to jquery)
fix for initial login render
updated unauth layout like main for 2.3.4
finished removing SimpleDateFormat
use legacy binding style (initially)
