Added SSL for MySQL database connections

I have added the ability to connect using SSL to a MySQL database.

The following options have been added to the videodatabase/musicdatabase sections of the advanced settings XML file.

		<key></key>
		<cert></cert>
		<ca></ca>
		<capath></capath>
		<ciphers></ciphers>

All of these new options are completely optional and are silently ignored if defined when using SQLite. The options follow the specifications as defined for the mysql_ssl_set() function in MySQL 5.0 and later. See the following link for details http://dev.mysql.com/doc/refman/5.0/en/mysql-ssl-set.html .

I have tested this update on Windows 8 x64 and Fedora 17 x64. I found no problems.
