Updated the manifest
Updated ignore.txt
Renamed t/01-force.t to t/01-basics.t
Use t/10-prototypes.t to test that predeclarated subs with prototypes can be lazified
Make the dependency on Devel::CallChecker dependent on the perl version.

This way, on newer Perls, I can test this module on blead without
actually having to install anything.
More realistic requirement for the "require VERSION" -- I can't even install Perl 5.6, much less support it
Proper checks and errors for import(), support for \&coderef => "proto"
Several doc improvements
