safer conversion of grape accepted types to swagger types

[jdoconnor]

This allows for the grape accepted param type 'Boolean' to be converted properly to a swagger type. The issue is that the full type of a Boolean includes the Virtus namespace. This can probably be extracted for other Virtus types

Looks like the tests are failing in this branch. If you still want this in, can you make tests succeed (and rebase on master)

[jdoconnor]

@tim-vandecasteele good to go! Thanks for reviewing.

Please merge this next. I've run into this problem.

@jdoconnor You should rebase if you see this. Thanks.

[jdoconnor]

@dblock rebased. tests passing. I haven't been keeping up to know if this was still a problem or not. hopefully this unblocks those that need it.

What's missing here is a test for the Virtus type. You're adding functionality, it should be tested :)

I believe this can be closed, fixed from #168.

[jdoconnor]

agree.
