/* \brief Addon versioning using the debian versioning scheme
AddonVersion uses debian versioning, which means in the each section of the period
separated version string, numbers are compared numerically rather than lexicographically,
thus any preceding zeros are ignored.
i.e. 1.00 is considered the same as 1.0, and 1.01 is considered the same as 1.1.
Further, 1.0 < 1.0.0
See here for more info: http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version
