Aiue:
    - Made the previous fix actually work rather than breaking the function completely. (0/0 = -1.#IND = ALL the numbers\!)
    - A factor of 0/0 will now be defined as 0 within GetAngleGradient() rather than being neither validated nor redefined.
    - #@debug@ in .toc does more than advertised and also adds a space, apparently. Fix due to this.
    - Less zealous validation provides behaviour more closely matching definitions.
    - Minor versioning pokage.
    - Fixed a few errors that should've been caught by testing before even making it to alpha.
    - \'@project-timestamp@\' makes for a bad minor version.
    - Added validation to the conversion functions.
    - :GetAngleGradient() rewritten to only accept raw numbers rather than tables or strings. (Thanx Phanx)
