Gamma measure

[gdalle]

Hey @cscherrer
Here's the implementation of the Gamma measure based on the version from Distributions.jl, with both standard parametrizations from Wikipedia.

Thanks @gdalle . This is looking good, I think we just need a few more functions and some tests.

Weirdly, tests here are failing, for code that passed before, passes locally for me, and is completely outside your changes. I don't think there's anything for you to do about that, but I'll need to figure out what's going on.

EDIT: I figured it out! A test was incorrectly passing before I fixed some things in the last MeasureBase. I'll change it so it passes again.

What kind of additional functions did you have in mind?

[cscherrer]

Sorry that was vague, the failing tests had me pretty distracted. Offhand I didn't see a method for testvalue. We'll also need some tests. Could you add some similar to other parameterized measures? These are in test/runtests.jl. In general we really need to improve our test coverage.

Thanks again for your work on this :)
