AJAX form submit bug

Hi, I've fixed a bug resulting in some of the settings loosing their value. This happens when the Edit CSS form in Wordpress (3.5.1) administration is submitted. Then the save action for the "Advanced Search by my Solr server" is triggered and the settings for the self hosted instance are lost. It is very annoying. I've changed the way the ajax actions are processed.  Аlso fixed a bug with the percents not updating while the index action is running.
