Updated gitignore.
Replaced MIT license with new BSD.

They are similar but BSD is standard for Spree modules.
Updated Versionfile with new master branch version.
Updated EN locale with spree i18n namespace.
Replaced Swedish and Norwegian locales.

Swedish should not use dialect style but follow rails_i18n standards.
nn.yml is for Nynosk but translation is bokmål so it should be nb.yml
Add Finnish locale.

Yes, it probably need grammar corrections :/
Refactor engine for Spree 2
Cleanup.

Spree i18n namespace and new 1.9 hash syntax. This version is a fresh
branch for Spree 2 so I found it a good starting point to have cleaner
code to work with.
Add klarna_payment factory.
Add some base specs.
Add travis config.
Updated readme.
