Case Insensitive Routing

[Russman12]

We would like the ability to make case insensitive route calls. In other words, if we have set up a route to /my/route we would like a call to /MY/ROUTE to hit that route. I could not find any documentation explaining how to do this in the current project. Is this already possible? If so, how? If not, would it be possible to add it as a feature? I'm happy to help develop it, but not sure exactly how it ought to be implemented.

This isn't implemented right now but I'm happy to take a PR for it.

Aside from tests and docs, I think these 3 changes are needed:

1. Add a CaseInsensitive boolean option to the TreeMux object.
2. If it's true, then convert path to lowercase at

   httptreemux/router.go

   Line 129 in b61bfc4

   trailingSlash := path[pathLen-1] == '/' && pathLen > 1

   and probably unescapedPath later where it's actually used.
3. If it's true, convert thePath to lowercase at

   httptreemux/group.go

   Line 147 in b61bfc4

   node := g.mux.root.addPath(thePath[1:], nil, false)

I think that should do it!

Thanks for the quick response. I'll make a pull request when I have some free time.
