Bug #608032: Handle MySQL connection timeouts with reconnect

Browse Source 
Patch by Tom van Braeckel:

For the full discussion, see the mailing list:
https://lists.gnucash.org/pipermail/gnucash-devel/2010-February/027323.html

Rationale: When we try to open a database transaction, and the database reports
that the "server has gone away", we try to reconnect before failing hard.
