Add server.log and journal.log to nightly build

Turn on journaling using journal.econfig.
Append the server.log and journal.log files
to the nightly build log in the SERVERSTOP step.
Remove the server.log and journal.log in the
SERVERSTART step to ensure only this run's log
events are included in the nightly build log.
Add the construction of a econfig in the
generate step using *.econfig in the patches
directory in a same way code patches are applied.
The mingw.patch was removed and replaced with the
mingw.econfig.  The mingw.econfig also required
the addition of exports to the win32.i386.config.
