Pathfinder exploit patch.

If the enemy is not found, he not taken into account in pathfinder calculation.
Aliens can to open door and to kill standing behind door soldier.
small changes in cursor behaviour.

the selection box will now disappear when the cursor moves over the control
panel, in an effort to reduce accidental misclicks.

the selected unit arrow will no longer be occluded by ANYTHING.
i think this is some sort of falling code.

it looks as though there's a bunch of other stuff in there too..
i kinda remember something about weird pathfinding when going up stairs,
oh yeah, and i think i streamlined something so that it doesn't iterate
for large units.

not sure, pretty tired. leave a message on the forums to let me know what
i broke.

Fix Medi-kit exploit.

In CE, you cannot exceed maximum health.
In early DOS versions, it was sometimes possible to overflow the health stat so the soldier would be healthier after healing than he started before he was shot.

Fix to the VS2008 project
Fixed: Busy people don't get paychecks
Fixed: Odd manufacturing behavior when using too many engineers
Now it is possible to produce more than one unit per hour. (but items got built only on hour basis)
this looks like some sort of WORKING falling code
remove some redundant code

no need to blit the arrow twice
allow bugged behaviour for large units.

allow large units to have their inventory accessed while in debug mode
so we can use whatever bug resets TUs in the inventory screen to our
advantage.

did i say bug? i meant feature. it's a FEATURE.
