More enums

[hatRiot]

I hard code quite a few strings (stuff like platform names, versions, etc). These should be extrapolated to enums so we can quickly add/remove/change strings/lists at will. sqlmap has an enum for absolutely everything, but if they need to change something, it's all in one place.

An example of this was when Coldfusion 11 support was added. It'd be easy to modify a single string.
