+ new file for GUI-related mouse events handling (old mouse.inc renamed)
gui/button.inc and gui/window.inc:
* refactoring in regards of new mouse.inc:
* obsolete code eliminated
* old'n'ugly `check_buttons` and `checkwindows` removed
* events handlers added
gui/window.inc:
* moved GUI-related syscalls and auxilary functions from kernel.asm
* removed registers cross-ordering from syscall 67 (window move/resize)
+ more comments added
known bugs include:
1. apps using syscall 67 (kfar etc.) may not redraw their old screen area leaving ghost images
2. possibility of mouse cursor artefacts may have increased (this *really* has to be reworked)
