Console 1.30 released

After a while, here's Console v1.30

- a small window sizing fix (with regular border)

- window scrolling with background looks as it should now

- changed 'stretch' attribute of 'image' node to 'resize'

- added 'refresh' attribute to 'console' tag; it controls how often the console window redraws if there are no changes detected in the console; this timer is neccessary to ensure proper operation of some DOS programs (like RAR); this
refresh timer can be switched off to reduce CPU usage, but some DOS programs will not be displayed correctly (if at all :-)

- fixed Console crash if cursor style was set to 'none'

- real console can have any background color; there was a problem with non-black console background and Console background image (please read instructions for background 'color' tag regarding background images)

- added 'shell' attribute to 'console' node to override COMSPEC variable

- improved window painting a bit

- added background tinting for background images and fake transparency
