`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.
>Replaced dd_text2list, dd_text2listcase, tg_text2listcase and tg_text2list with text2list and text2listEx. text2list will return a list of each and every character in the string if you set separator=""
>added return_file_text(filepath) which returns text from a file after doing some checks: does the file exist? is the file empty? It prints helpful error messages to the world.log if it runs into problems
>Replaced dd_file2list(filepath, seperator) with file2list(filepath, seperator). It just calls text2list(return_file_text(filepath), seperator). rather than copypasta
>Replaced time_stamp() so it's not as retarded
>Lots of the world setup stuff uses file2list now, rather than file2text -> sanity -> text2list
>Added error() warning() testing() procs. These print messages to world.log with a prefix. e.g. ## ERROR: msg.
