1) Added English version of installation file.
2) Added /catalog/includes/languages/english/avsearch.php
so now AVsearch supports English language.
3) Added //catalog/includes/languages/turkish/avsearch.php
so now AVsearch supports Turkish language.
4) I removed unnecessary php files from contribution.
Instead, I updated English version of installation file for an easier installation.
This AVsearch is different than DropDown contribution so I named it as AVsearch v1.1
I installed this contribution and tested, it sometimes worked and sometimes waited long time,
so I think it needs to be get advanced more.
AVsearch now supports English, Spanish and Turkish.
This is a FULL PACKAGE, so have fun!
