Define types for special variables TimerA and TimerB

[MiranDMC]

Currently timera and timerb are predefined constants.
It seems like the types of underlaying variables should be predefined too, so there will be no need to add

var
TimerA : int
TimerB : int
end

to every script.

Maybe $ONMISSION (and other predefined variables) could be handled in same way too.

interesting. timers are usually used with number constants, like this:

TIMERA = 0

while TIMERA < 3000
    wait 0
end

so the compiler would use integer opcodes. I agree in principle that they could be declared by default as int variables, just curious to see the code where it is needed.

Real example:
0@ = DebugTimeOffset
0@ += TimerB
008F: 0@ = integer 0@ to_float
0@ *= 0.001 // ms to seconds

File constants.txt is implicitly imported in any script as a source file. It means that it is possible to modify the content of it to include a var..end construct.

For example, for data\sa\constants.txt:

const
false=0
true=1
TIMERA=32@
TIMERB=33@
end
var
TimerA : int
TimerB : int
end

Note to self: this breaks main.scm compilation as the compiler does not expect var..end to go before a DEFINE header.
