Query targets (such as NPMJS, RubyGems, PyPi etc.) can now be configured in the settings page. See the settings page for an explanation of the syntax. The extension comes with a default configuration which consists of the following targets:
- NPM JS
- RubyGems
- PyPi
- Maven Central

Added RubyGems to possible repository sources, and added attributions for open source libraries and graphics used.
