Commenting ModuleExplorer actions code
Removing "Rename Module" functionality from ModuleExplorer

It's not renaming all html text that carry the module name (think
CompiledFunction.fullName being used all the way), it will be a lot of
work to do so (not to mention implementing it fully, to renaming the
module file, the interpreter entries of the module etc) and this is not
something that will be used frequently right now.
Deleting function also removes it from the menu
Adding a function also adds it to the menu
Added eval() action to ModuleExplorer
