Release notes for 1.1.0

* Big update, which moves the project to a 1.1.0 point release
* Perform disabled check earlier in execution to prevent any interaction by plugin with websites when disabled
* Style enhancements to popup.html
* NEW user controlled domain settings! Users can now control scan and sanitize based on a site-by-site basis. Have a problem with a site? Disable either scan and/or sanitize and the plugin will avoid interaction with any CSS loaded by the website. Bug reports for site-related problems are still welcome!
