std/math_mod macro

[Woccz]

Dependent on #50.

I think it would be good to define a mod(x,m) macro in the standard math library.

I've implemented the mod for my own project.

In std/math_basic.nolol

macro mod(x,m) expr
    x-x/m/1000*1000*m
end

In std/math_advanced.nolol

macro mod(x,m) expr
    x%m 
end

(Macro definitions assuming #55.)

Thank you.

Seems reasonable. In the long run, once #50 is done, there should be replacement-macros for all build-in chip operators (except for these that are available on all chips).

Done. Published as part of v0.1.5
