Fixes rare crash on base facility dismantle

Deleting a base facility at x=2 y=3, so roughly where the ok button is
in the confirm deletion box, can occasionally cause a viewMouseOver
event to fire where the facility just was.

Marks the facility as being dismantled
Mark facility for dismantlement after user okays it
Reset selected facility when user dismantles

To avoid mouseover bugs on facility dismantlement, reset the selected
facility and remove it from our stored view.

Update CHANGELOG.txt

Update changelog as per next GIT push. Added some more explanation to some previous changes.
quickly check if a position is in our view.

New function for Battleunit, uses MATH!
surprise! no reaction fire.

adds the element of "surprise" by popping the state if new units were
spotted, prior to the reaction checking.
no TU cost for turning during reaction fire

and continue turning if we're shooting, regardless of "new enemy spotted"
add divisibility to Position objects.
change handling of reaction fire for projectiles.

target only goes aggro if it gets HIT, not just when targetted.

reaction fire occurs regardless of "potential victim" scenarios

refunds TUs for reaction shots if the target has died
(presumably from reaction fire)
allow for explosive efficacy function to be called externally

by using an extra case for an already existing argument.
don't push a projectile state here, reaction fire function will do it.
complete re-write of reaction fire functionality

addresses issues with visibility (units seeing in the dark)

completely reworks reaction fire to be MUCH closer to vanilla behaviour.
now allows: reactions from multiple units to a single action,
and multiple reactions from a single unit to a single action.
fix a difficulty bug

unit stats weren't being adjusted on game load.
now they are adjusted on unit creation instead.

also, fleeing aliens are eligible for reaction fire.
remove some unnessecary vars.
