revert Armor class constructor
Make last two locations for data available even if XDG_DATA_DIRS is defined in system.
This can be required for non-standart datadir locations, defined at compiletime.
Added compile-time option DATADIR for CMake.
This option can define custom place for datafiles via -DDATADIR.
If this option left undefined, data will be installed to "share/openxcom"
dir (expanded to /usr/share/openxcom).
Same goal can be achieved now with autotools by executing
"./configure --datadir=/usr/share/openxcom"
fix double animation on lightning door.
add points for base alien destruction

seems we were missing a score bonus there.
rewrite of unitOpensDoor() function.

the previous incantation was a wretched nest of if statements, questionable
logic, was difficult to follow, didn't work properly under a range of
circumstances, was inefficent, and was filled with "scotch tape" from being
"fixed" too many times.

a complete rewrite was therefore in order.
this should be more robust, easier to follow, function properly under most
if not every circumstance, is efficient, clean and has that new car smell.
Typo
Gentoo ebuild.
Make sure sprites get updated after turning.
Stop overCharging aliens.
remove diagonal handling for doors.
slight alteration to getTUCost to better handle stairs.
Globe shading can be rendered in diffrent base resolution.
modify bigwall flag to integer

this will help us better define how to behave around certain "bigwall"
objects we encounter while pathfinding.
removes the hack for landing craft walls.
implement ruleset-based MCD patches

while this class does require expansion to accommodate everything that
defines a mapData object, it does provide a "good start" that should be easy
to copypaste all the rest later on. for now i'm just adding in some bigWall
integers to differenciate them a bit, for the improvements to the
pathfinder.
fix compilation error.
Revert "remove diagonal handling for doors."

This reverts commit 24faaa018c20ddc81abc907d83d206b54ba8cfca.
Replace deprecated malloc.h with proper stdlib.h
