helixhorned 5cb6e20c63 Add new actor flag and predefined CON label SFLAG_NODAMAGEPUSH. 
This flag is set from C for some enemies that should not be pushed back when
damaged, such as TANK. Both the tile flag and the per-sprite flag are used
(i.e. the ultimate flag value is the XOR of the two).
Add currently non-functional example to test.lua that attempts to set this bit
for NEWBEAST.
