v3.99.5 released - new feature to allow user override of hard-coded ProBalance exclusions

I've had many users request I allow them to override hard coded ProBalance exclusions. This makes perfect sense, as in some circumstances certain processes do need to be unexcluded. In fact, at least one of the processes on the hard-coded ProBalance exclusion list probably should not have even be there (it was removed now). I originally implemented these hard-coded exclusions because of my 'do no harm' rule. I always take the safest approach, as I feel that is my duty.

Anyway, I have completed this code, and it will be available in v3.99.5 alpha, now released. When you try to unexclude a hard-coded exclusion, you'll simply be asked if you want to over-ride the hard-coded exclusion. Previous builds would have simply told you the exclusion is hard-coded and can not be removed.
