RESOLVED - Bug 384051 - Custom column as a table: column filter is garbled
Bug 398505 - Rap: Context menus should be created only when needed 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=398505

Partially reverted the last change because the menus should be available from the beginning and not only if a file gets selected (as in swing ui). This means lazy creation is not possible for the fileupload widget.
Also removed unnecessary code as already done in the other dropdown buttons.
Bug 396845 - SWT: Max. row height should be configurable in multiline text tables

Applies patch by Oli Schmid: Smart fields do not use multinine tooltips anymore. Fixes focus bug of multiline tooltip.
