Subject: plugin version compatibility checking. To use, set MinVersion,
 MaxVersion or MinPHPversion in the plugin header block. Case is not
 important. We check the project versions against STD_VERSION, which should be
 rolled to a new y of x.x.y if the plugin interface or project code changes in
 an incompatible way.
