forked from KolibriOS/kolibrios
1. a little fix for scheduler + correct comments
2. refactored window activation/ process termination/ getting active process 3. deleted dead code in checkwindows 4. eliminated almost all accesses to 0x3020+...+0xe, changed to direct process number 5. cli/sti in vesa12 and vga drivers and in calculatescreen 6. skipping dead windows in some funcs in window.inc git-svn-id: svn://kolibrios.org@102 a494cfbc-eb01-0410-851d-a64ba20cac60
