MooseX::Declare dependency

First of all, thanks for contributing such a high quality module to the cpan.

But its installation could be speeded up by getting rid of MooseX::Declare as a dependency. Also sometimes Devel::Declare, that MooseX::Declare depends on, is a little bit dodgy to install under strawberry perl for windows.

Because you are using MooseX::Declare only in a single test, I was able to remove it and use builtin perl mechanism instead.
