`maths.dm`:
Rewrite `Gcd(x)` to remove recursive behaviour.
Remove `RaiseToPower(x)` and its usage from `event_manager.dm`.
Rename `Lerp()` to `Interpolate()`.
Add `Square(x)`, which squares a number.
Rearrange most of the functions in the file. (trigonometric functions together, etc.)
`type2type.dm`:
Rewrite `num2hex()` and optimise `hex2num()` for superior clarity and a 100% speed improvement.
Correct indenting, spaces, make switches more concise.
`time.dm`:
Remove old, slanderous commented-out function `/proc/time_stamp()`
`lists.dm`:
Add the macros, `BITTEST(bitfield,index)`, `BITSET(...)`, `BITRESET(...)`
and `BITFLIP(...)` for bit-manipulation and use them where 20+ files
do it manually, for arguments of reader clarity and standardness.
Basically, a more generalized version of the rune code,
split into more reusable procs. Plus one that generates
a version of an icon that has a neat bluespace effect
applied.
