Revert "Moose/WebGUI.pm/Module::Runtime/Plack::Component bad interaction #23"

Ooops.  Okay, this was related to MooseX::NonMoose and the bug has since been fixed.
https://github.com/doy/moosex-nonmoose/issues/12 for details.

This reverts commit 782ee7a1e3f15145ec01a8b7d9413f8bea0ef26c.
Bump the version of MooseX::NonMoose required.  Some previous versions had a bug where attempting to 'extends' a module without a VERSION would blow up, even though no specific version of that module was requested.
See 782ee7a1e3f15145ec01a8b7d9413f8bea0ef26c and doy/moosex-nonmoose#12
