0.3.1

Changes:

• Bug fixes for relative imports
• Bug fixes for when lookup_path starts with or is a dot (.)
• Added ignore_package_prefixes so that you can use a variable named e.g. foo to import a package named brigade-foo.
• Support for matching plural folder names, so that e.g. mockComponent matches foo/bar/mocks/component.js.

Thanks to @lencioni for filing a bunch of issues leading up to these enhancements.
