Changes in V1.6:
* Added Category column for search preferences
* Added preference filter for easy viewing/update of preferences

* Custom Search Engine -> Now you can search with multiple search engines in one go.
Type search engine keys separated with comma ',' (no spaces).
E.g. "ms key1,key2,key3 <search text="">"

If search engine key itself contains comma ',' then multi-search feature is automatically disabled.

* Preferences page -> Sort custom search engine data based on key, url or description

* Preferences page -> Better error reporting

Update to allow multiple search tags in search url upto 10 search parameters.

More optimisations on options page.

Added support for multiple platforms.
