Improved jQuery.timers initialization on partial page updates

Hi there,

**Problem:**
jQuery.timers initialization, when performed from partial page updates (for example, when parts of the page are loaded via jQuery.load), fails with various error messages (like "jQuery.timer not found").

**Solution:**
The problem is gone, as soon as we put jQuery.timers initialization into document-ready call. The suggested change in the source code is doing exactly this.

Additionally I added README.md and CHANGES.md.
