balance tweak - make turret armor heavy

Since turrets have wood armor, they can get killed by flame tanks uber fast. It might be best if turrets are a counter to flame tanks, rather than their prey. If they have heavy armor, they will take far less damage, and not die instantly to a flame tank rush, making them able to contribute to some defense.
Makes rank chevron palette customizable.

Adds levelup crate-effect and art.
Fix build palette showing too many queued items when BuildLimit is reached

When a BuildLimit on an actor type is set and nearly reached, you could
shift-click the build palette and it would show it had five more items
queued when really less are allowed to be built. This fixes it so that
only the allowed number of items is enqueued, and thus showing the
correct number on the build palette.
Make Wall its own TargetType

Going to make some units (machineguns, etc.) unable to fire at walls.
Certain units can no longer target walls

Units which cannot target walls (sandbags, chain-link fence or concrete) any longer:
Minigunner
Flamethrower
Hum-vee/Nod Buggy 
Flame Tank (can still run over sand bags and chain-link fences)
Civilian
[sniper--already so]
Adjust air strike so it kills turret

The recent armor change for turrets made airstrike no longer killed it. 

Made Napalm do more damage to Heavy (and light); made Vulcan do less damage to Heavy so that airstrikes don't do too much damage to advanced towers, obelisks and SAM sites.
Remove unused and obsolete Cached.cs

This was similar to Lazy<T>
Remove custom Stopwatch wrapper

Remove the redirection (that doesn't offer any new functionality)
and replace it with the familiar System.Diagnostics.Stopwatch.
Replace (and remove) custom Set<T> with HashSet<T>
