Three test + doc fixes

Hello!

These three commits provide test and documentation fixes.

The first commit mentions cpanfile in the -Home section of Catalyst.pm, fixes a related test failure in unit_utils_home.t, and adds 'cpanfile' to spelling.t's stopwords.

The second fixes massive test failures cause by t/lib/TestApp/View/Dump.pm trying to call a method that had been renamed.  It also adds pod for the renamed method and provides a spelling.t exception for a related method.

The last commit just fixes the last two failing tests in spelling.t.

If you'd like me to rewrite/reorganize any of these commits, please let me know.  I'd be happy to.  Thanks for your time and effort and have a great day!

Cheers,
Fitz
