Improve faulty context menu extension handling

[deafff]

Hello,
I have a problem with context menus failing to show up after installing faulty context menu extension.
Now, I know this is not a problem of Total Commander per se, and can be solved by hunting for the extension with ShellExView, but this problem comes up a lot, and some users probably do not posses the skill/time/will to do it anyway.
Maybe it wouldn't be a bad idea to make TC's handle these kinds of errors gracefully. I'm sure it can be done, as Explorer and DOpus have no problem with it, and it's probably couple of ifs at most.

In my case, the problem appeared with Miranda-NG's 0.95.3 build 11706 (latest as of today) Shell extension plugin, "Plugins\ShlExt.dll" on Windows 7 64bit.
Hope it will help you sort these problems out for good.

The problem is that TC cannot even control this - TC just calls IShellFolder->QueryContextMenu, and receives the completed menu (or a crash). I have a try..except block around this call to catch exceptions, but some plugins create separate threads - when they crash, there is nothing I can do.
