1. a little fix for scheduler + correct comments

Browse Source 
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
