WebCore:

Added EditingUnixBehavior editing type aim to cover the cases when
neither Mac or Windows behaviors are appropriated.

It was decided to name it Unix not Linux.

No new tests. The current editing tests that involve platform specific
bahaviors are coded so that they go through all editing behavior
types possible. There will be a follow up bug where all of them will
be updated to include the new editing behavior ("unix").
