Updated all the extension.

Today I was told that some PHP errors and warnings are displayed after searching a content. It looked like it did not happen to my development environment. Luckily I could have thought I should have checked the log from Apache and found the situation was actually happening.

I have just finished fixing them up and have uploaded all the extensions. So please upgrade all the extensions which include both Easy Search and the plugins you use at your website.

I appreciate your feedback.
