Adding info about the Mac UB port and cleaning up the grammar 

Hi, after a few thousand posts over at the Newtek forums I decided it was time to clean this baby up. I'm not changing anything major, just removing some irrelevant links and redundant history (the intro paragraph says stuff about the Amiga that is also said in the History section. Also I'm trying to give it a more neutral POV.

Does anybody have some updated screenshots? The ones on there are from 9.0 which was almost 3 releases ago...
