Subject: [PATCH] Forward Total Commander Lister view-mode keys (1-8) to the
 parent Lister window

The IE WebBrowser control and the RichEdit raw-source pane were consuming the
WM_KEYDOWN messages for the digit keys 1-8, which Total Commander uses to switch
between Lister view modes. Intercept those keys in the subclassed window
procedures and post them to the Lister window (the parent of the plugin
container) so TC can handle them again.

Fixes the 1-8 view-mode shortcuts while keeping the plugin's own Ctrl+* hotkeys
and internal navigation intact.
