Implemented:  FS#2388 - Optional confirm window on changing tabs

Corrected paths in main tpl

Moved old default theme to themes/default-304

- Added Tipsy (http://onehackoranother.com/projects/jquery/tipsy/) so that one can create tooltips for additional explanations easily.

- Added search box to other templates as well.

- Added translations to global search.

- Introduced subsections for forms. With subsections, you can split up large forms. Subsections can be slid into/out of view.

Fixed bug that caused the wrong list to be loaded when the return key was pressed in a search text field of a list.

fixed #681 - removed all onblur, checked onchange for function and removed it in filter panels. Added jquery keypress (event 13 -> enter) and tested it in different browsers
