Added the ability to compare to the terms synonyms.
Fixed a bug where all the terms except the found term would be removed from the node if a match was found.
Adding the following plus keyword filter.
* Add a summary of new terms to user.
* Add functionalty to delete the node if in a vocab using feedapi_after_parse
* Add option to delete the original term if it is no longer assoicated to any nodes
Changed code to use feedapi_after_refresh. Now feedapi_taxonomy_compare works with feed element mapper correctly.
Update Readme and required dependencies.
The options are not global instead of per content type.
