"be" conjugated as a gerund returns "being"

[zischwartz]

Here's an example of the behavior, basically:

let opt = {
     form: RiTa.GERUND,
}
let result = RiTa.conjugate("be", opt)
// returns "bing" instead of "being"

Maybe I'm missing something? Looks like there's some special handling for this hereish.
