Image painting 2D:

Deprecate wrap (BRUSH_TORUS) option, we now have paint flags for tiling
and we can reuse those. Also allows seperate tiling in X/Y
direction for 2D painting now.

Only one tiling is allowed for now.

Options can be found in new "Tiling" panel under the tools tab.

For version patching, we just turn off brush wrapping,
to allow reuse of the flag in the future.
New option is paint mode wide instead of per brush so
a brush having the old wrap option will not enable it
for the whole mode in the version patch.
