WebSearches for Big Cat 1.1

WebSearches is a script for the Big Cat context menu plugin (available on VT and at http://www.ranchero.com/bigcat/) which allows users to add web searches for highlighted text. To add a search, users must first run a sample search in their web browser and copy the URL containing the search terms, then enter the URL into WebSearches with the search terms replaced with "###SEARCHTERMS###".
