Change from ::AutoEscape to ::AutoEscaping.

I (= Shlomi Fish) am forking and rebranding the module under a
different name because that's what the original author has instructed me
to do to continue development of it.
Add the new changes.
Fix the README.
Bump the version number.
Add missing dependencies - especially 'URI'.
Bump the version to 0.0301.
POD validation.
Add more.
