Handle Synonyms (patch included)

Problem/Motivation

Google appliance may return search term synonyms, which are being ignored by the module.

Proposed resolution

The attached patch follows code examples for handling other elements (e.g. keymatch). It parses the xml in the module, uses template preprocess functions to check the parsed data and generate links to synonym searches and displays the results with a new template file and some css rules.

Remaining tasks

quality control.

User interface changes

If synonyms are returned, they appear as links under the search box on the results page, labeled similar to the google appliance default, "You might also try:".

API changes

None
