in Error(0) the palette was not properly restored
as it was always restored to the Main_palette.
Now we really restore the right palette !
Also clarified/simplified the change directory code in case of error.

Bugfix there was no Atari_Memory_free() declaration when __MINT_ define was declared.

* To avoid the program getting 'locked' when there is no user input (sliders, colorspray), we use a timer that queues events to make grafX2 act (and refresh the screen)
TODO :
* To reduce cpu usage when idle even more, start the timer only when it's needed (colorspray is drawing, or a scrollbar is scrolling)
* For now everyone uses the same timer, so the same delay. This means there is no fast-scroll and slow-scroll for sliders. Starting the timer with a different speed in each case would solve that
* The event handling for sliders will currently react to any mouse event. Thismeans the slider will move faster if you slightly move the mouse while keeping in the button. Not what wewant, so weshoud all a timer_expired global and the slider should wait for that (and reset it when acknowledged).
