Support category wildcards in complex form armorial descriptions

[mathghamhain]

There are times when you'd like to search for any type of charge that met certain conditions.

For example:

• GU|AZ, *:primary:sable — to find red or blue fields with black primary charges
• PO, BORDURE:argent, *:tertiary:vert — to find white bordures with green tertiaries

This would require some new functionality in the database server.

This functionality was requested during the "Under the Covers of oanda.sca.org" at eKWHSS last month.
