Editor won't start; "This Widget is already attached to the User Interface"

[rikus]

Here is what happens:

bool Simulation::SetupToEdit() (Info) - Simulation Edit Setup Complete
bool Simulation::Edit() (Info) - Simulation Edit Starting
virtual Container* Container::AddChild(Widget*) (Info) - Adding Button Alliance 0x80fb87470 to Master
virtual bool Container::IsAttached(Widget*) (Info) - Found Button Alliance (0x80fb87470) in Master
static int Lua::ErrorCatch(lua_State*) (Error) - Fatal Error in Lua 'error running function `componentDebugger': Resources/Scripts/editor.lua:7: bad argument #2 to 'add' (This Widget is already attached to the User Interface.)'
Assertion failed: (0), function ErrorCatch, file Source/Utilities/lua.cpp, line 208.
zsh: abort      ./epiar

And I noticed that this patch to add widgets individually rather than all at once will work around whatever the problem is:

It looks like this is a typo in the addWidget Function (the method works), where only the widget was being added to the UI over and over.

-		Widget* widget = checkWidget(L,1);
+		Widget* widget = checkWidget(L,i);

I'll push a fix ASAP.
