Summary: Wx::ListCtrl will crash if item added before insert_column called

Initial Comment:
If Wx::ListCtrl has been created with Wx::LC_REPORT style (to show multiple
columns and rows, with optional icon), it will SEGV if insert_item is called
before insert_column is called.

Doing this (inserting an item before inserting a column) in user code is of
course incorrect, but WxRuby should signal this mistake more courteously than by
crashing.

The relevant line thrown in the crash is:

wxListMainWindow::InsertItem 

at ../src/generic/listctrl.cpp:4541
wxColWidthInfo *pWidthInfo = m_aColWidths.Item(item.GetColumn());
