Simple API version tracking

This isn't anything over the top or self maintaining. However, it should cover the need, with a little manual input, which version of Each api UE compatibility module was created with. Current this is missing and i've noticed some issues with helping user when it comes to API version errors/crashes. Especial when the only thing to work with is the version of the mods.

This should later be expanded to do basic version checking and suggest to the user that for best use to update or change mod versions. Though this does rely on the mod using the API to call the init method.

Also after pulling this someone will need to manually add the API version to the build.property file. Currently i have no clue which versions of the APIs UE has in the repo. This is mainly the reason why i created this so myself and other can look at the console for versions as well the build.prop file.
