Add support for extracting IdP details from metadata xml
Removed unused variables and made xpath selectors more specific
Add class AttributeValue that fixes onelogin#117
AttributeValue is a String, but `AttributeValue#values` will return
all values for that attribute.

Require AttributeValue class in correct place

Add support for extracting IdP details from metadata xml
Added Ruby 2.1.1 to travis
Bumped ruby 2.1.2, removed unsupported ruby-debug
Added license to the gemspec
moved back to 2.1.1, some gemfile modifications

Added a Bundler.require so that bundler will manage the dependencies.
Uses ruby-debug for ruby 1.8.*, and uses debugger for anything else.
Also, seems as if the debugger gem has yet to support ruby 2.1.2, so
moved back to ruby 2.1.1 for now.
