Switch to carton for dependency management

[link2xt]

Carton is a Perl dependency manager that supports lockfiles (cpanfile.snapshot) which ensures that the same versions of Perl modules are used in deployment as the ones used for testing. This way dependency management can be unified for various operating systems.

I have created a PR #252 to add cpanfile, which moves requirements from Makefile.PL to cpanfile, which can be used by Carton. So far it is still used by cpanm.

I am going to submit a work-in-progress PR for carton support, but now I have problems compiling some Catalyst modules in development environment.

Byt the way, there is a comment about carton in the source code:

# perl dependencies. Probably switch to use carton

Closing because #265 is merged.
