Add ability to define patterns in order to have a session (depending on configuration) either automatically created or automatically added to an existing session for URLs matching the pattern.

In user stories:As a user I want to have a possibility to define patterns to start a new session so that URL matching a pattern create a session without my interactionAs a user I want to have an option to configure the plugin to create a new session for an URL pattern matching an existing session based on the same pattern so that I can have separate sessions based on the URL matching the same pattern.As a user I want to have an option to configure the plugin to add a tab with URL pattern matching an existing session based on the same pattern so that I can have multiple tabs in an existing session based on the URL matching the same pattern.

Example:As a user if I go to www.google.* I want to have a new "Google" session created (or tab added to current "Google" session) for all URLs where the host part matches the www.google.* pattern (www.google.com, www.google.de, www.google.be, www.google.pl and so on)

Hope this is clear :)
