Updated the HttT animationwml to the new syntax
Ran wmlindent
Updated leading anims for the HttT units
SotBE S2-8: put type= key back into Side 1 [side] tag

This is not actually needed (as in, it works just fine without for
sides carried over), but wmllint complains about it.
Changed the scope of side controller lock.

The lock is now per side, not per scenario. The lock has also been
renamed to "controller_lock".

Additionally, the game should now not apply a lock if "controller"
attribute was empty.
Refactored a method in mp::connect_engine.
Added "controller_lock=no" for multiplayer maps.

These changes guarantees that it will be possible to select any kind of
controller in MP Connect screen in all multiplayer maps.
Added missing side attributes to team::attributes array.
AnimationWML: minor animation macro cleanup.
minor sound timing change for red mage line fire attack.
minor change to unit frame redraw internal parameter to better reflect function.
Made it so the Sleeping Gryphon is never quick
Changed the sleeping Gryphon code in Gryphon Mountain
Changed the way Sleeping Gryphons awaken
