Subject: Mysql#reconnect is set according to the 'reconnect' key in the
 connection spec.

The 'reconenct' boolean option is read from the connection specification
and is used to set the reconnect attribute of Mysql.  The default is
false in order not to change existing application behaviour.

Also, reconnect is set AFTER real_connect is called, so its value sticks
(the mysql gem sets reconnect to false inside real_connect).
