[Improvements]
- Improve the error message on bootstrapping
- Implemented experimental -L|--local-lib-contained option to install module
and its non-core dependencies into local::lib directory
[Developer Fixes]
- Use Module::Metadata and avoid calling another perl interpreter
to check the installed versions of the modules
- Also dump @INC into a file DumpedINC.pm when self-contained is enabled
- Set PERL5_CPANM_IS_RUNNING in configure
- Changed the way to pack modules into a file, now using App::FatPacker
