Added the perlbrew init command and version of perlbrew changed.

After installing perlbrew and checking the version available,
the perlbrew init command should be run before proceeding
further to install a version inside perlbrew.Also the version
of perlbrew to install is changed to perl-5.14.4 (from perl-5.14.2).

Work in progress for #316. I finished proof reading all of
Cookbook.pod. Fixed spelling errors, formatting, code and broken links.

Haven't still checked code samples by actually running, but I did read
through all code to verify correctness.

basic tests.
Work in progress for #383. Added tests for session flush, retrieve and
destroy.
Finished nearly all tests for #383 however session retrieval is acting
weird
Work in progress for #383. Added a new and working test suite
for testing session hooks.

Session hooks for Simple sessions are now tested. The framework is
already ready to make it use a YAML backend.
Tested session hooks for Simple engine as per #383.

This test suite still only works with Simple and not with more than one
backend. Possibly because I'm not setting it all up correctly. This
changeset also added LWP::Protocol::PSGI as a dependency into dist.ini.
I needed this to setup the dancer app and make requests to it within the
same process.
