We only handled events for wxID_FILE1..wxID_FILE9 range but there can be more than 9 entries in the MRU list. Handle events for as many of them as there are correctly. This required adding a fallback handler for all menu events and checking if the id of the menu item is in the MRU range inside it. Also move this to wxDocManager itself from wxDocParentFrameAnyBase as it's common for all kinds of frames anyhow. Closes #12141. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@64569 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
