With the older Community Builder 1.2 RC2 version, one patch was not necessary and the installation of the patches always failled because JMS was not able to find the peace of code to patch.

The result was that it was not possible to install all the JMS patches because JMS has detected its error and roolback the installation of the patches.

This new patche definition detect this specific CB 1.2 RC2 to ignore the patch of one file.

This patch definition also contain some patches required by JACLPlus.
The patch allow to create slave site when JACLPlus is present.
It also allow to login as administrator of the slave site event when the JACLPlus is not yet re-isntalled.
The problem identified with JACLPlus was that it patches a lot of Joomla files to check the permission in DB.
Unfortunatelly, it also do that during the installation of a new slave site that is by definition does not yet contain any user permission definition as the DB is not yet created.
A similar problem was also detected when trying to login as administrator as the JACLPlus table does not exists yet in DB because the JACLPlus extension has not been re-installed.
The patches has consisted to detect those two cases an enhance JACLPlus patches to avoid this side effect.
