Integrating unrar 5.90

Today I've been testing some new components of Icaros Desktop, including unrar 5.90. I had to modify ZuneARC'c configuration file, because the stack I already set for version 5.80, 400000, wasn't enough. I raised it to 800000, and now RAR archives can be easily managed, as the following screenshot demonstrates. By the way, what do you think about this Commodore-128esque font?
