By default, do not install the PI Module Database Builder when the PI System Management Tools install kit is run
Similar to how the PI DataLink install kit includes PI DataLink (Legacy) but requires manual modification to setup.ini in order to install it, the PI Module Database Builder should continue to be included in the PI System Management Tools install kit but should not be installed by default. This will make it clearer to users that the PI Module Database is deprecated and it will declutter the list of installed programs for users that never used the PI Module Database Builder.

My comparison to the PI DataLink install kit won't hold true for much longer. According to the response to the suggestion linked below, PI DataLink (Legacy) will be removed in the next release.
