WSP Package for deployment

Created the wsp package for deploying the feature that contains the code
for processing items from the SearchLikeList, the dialog to allow the
user to edit the Search Like before adding to the list and all the
required JavaScript and XSLT files.

In order to deploy this still requires the SearchLikeList to be deployed
manually. Also requires updating the the Search Core Results webpart to
set the XSL Link property (under Miscellaneous properties) to /Style
Library/XSL Style Sheets/SearchLikesResults.xslt.
SearchLikeList updates

Added a template for the list.
Updated the xml file to include the Url field.
