Ed Sanders 84fbd1db2c Only undo on MWMetaDialog close if small stack is non-empty
Added return boolean to ve.dm.Surface#breakpoint to indicate if
and transactions were pushed to the big stack. Use this value in
MWMetaDialog to see if we need to undo on close.

Added tests for ve.dm.Surface#breakpoint.
