fixed colspan in cronlist, added min-width in combobox table td, added new trigger in combobox for onclick autocomplete to submit

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

combobox can send now focused with enter when a complete match exsits like 5 in priority in spamfilters

smaller tabs in no_image and 32x32, admin has under 1024 all tabs in 1 row and in no_image some space free for 2 more tabs

fieldset border-color set for all browsers @till blue looks in all colors bad with 1px, i used now gray + Remoteuser list, add user button has now a fieldset like every other form (i had without a problem in FF8)

empty value better see, ^Cigger is mouseover body (still better after ajax request), css fixes (chromium,FF,Opera,rekonq,IE), 1 sprite image in gray for icons
