In-Portal rebuilds category cache after a change has been made to a category.
Right now cache rebuild is always made. Following rules apply after category has been changed:
On one of my projects I saw a customization, when new setting was added "Automatically Rebuild Category Cache" was added and it was disabled. This was done, because there were 3000 categories and they were changed very often, so answering No all the time to "rebuild category cache now" question became very annoying.
I'm proposing to create new configuration setting "Category Cache Rebuild Mode", that will replace "quick category cache rebuild" option with following options:
Default setting will be set to Automatic for backwards compatibility.
