Aiue:
    - 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)
