Grant licenses of one type exclusively?

[sanmai-NL]

Since the project is still small, this is the best time to bring up a boring and annoying, and probably unimportant licensing question.

I just learned that dual-licensing actually makes no sense.

See hyperium/hyper#1277, in particular seanmonstar’s comment:

Apache gives a mutual patent license, so anyone suing the project automatically loses any license they received using it. However, the dual license allows someone to sue while simultaneously just using under the MIT license. I don't expect to be sued, but bleck.

Now that there a very still few committers there is no problem with authorship, you can remove the MIT license. This applies to other crates too, but I'll just open an issue here.

Based on the other comments in that issue, I think I'd prefer to go the other way and make it MIT-only, or possibly MPL-2. But, this is also another instance where I'd rather follow the larger community/ecosystem instead of leading it.

Going to keep this as is for now.
