Fixed loading of namespaced gems and added BEXT_VERBOSE

[lzap]

This was never working on 0.4, regression from 0.3 version.

If you can bump upstream we would be pleased. Thanks!

Hey @lzap, ran through this, looks good. Just to clarify, this is to address the case where the dep cannot be required but the namespaced file is nil, correct? In that case we should not throw the strict_error. The error should still be thrown if the namespaced file is not nil but cannot be required.

The only blocker that I see on my end is a few of the specs are broken with this commit, namely the ones that test the current functionality. After those are changed/removed, don't have any issue w/ merging. @jguiditta thoughts?

A couple small style issues (not blockers). Would prefer adding a helper to the Output class that writes to stdout and use that instead of using 'puts' directly. Then we could easily override that method with another to use the rails logger or whatever other custom logging mechanism.

Also for consistency, perhaps the setting of the 'verbose' variable could be moved to a 'parse_env' helper (eg see the 'System' and 'Output' classes). Again just nitpicking :-)

Right, I totally forgot we have unit tests now. Helped to catch me the bug. Can we set Travis CI on this project now? ;-)

Fixed the missing strict error, moved the verbose thing to Output class. Good catch. Tests are green. TY

I've tested this, it seems to fix the issue of loading namespaced gems (such as fog-core) seen on 0.4.0, which worked on 0.3.0.

Could this be re-reviewed please?

[movitto]

OK, merged. Tests are currently broken due to incompatibilities with more recent versions of rspec but that's a separate issue.
