Removal of unnecessary overrides of jquery-ui styles

ipa.css had to be updated to work with updated jquery-ui. This patch removes several duplicate styles.

Following issues were fixed:
 * dialogs titles in IE and Opera were black instead of green
 * no black line in first navigation level in IE and Opera
 * all browsers (FF, IE, Chrome, Opera) have the same style for buttons and headers
 * dialogs has borders again (should we remove its shadow?)

Known issues:
 * selected tab-1 in Chrome and Opera doesn't overlaps background line as in IE and FF. Not sure how to fix without breaking (there are border overlaps) the latter ones. I think it looks good enough.
 * some buttons are missing padding. Will be fixed in next patch.
