Bug 33216 Source actions in context menu on types inconsistency
1) select a type in the package explorer 2) bring up the context menu ->the source actions are shown in-line and the menu is huge. Given that we show a source submenu in other parts (e.g. the editor) and do the same for the refactoring actions we should also move the source actions into a submenu.
