Feature: Add icons to experimental features submenu

Add 16x16 menu icons for the three experimental-features items in the
online-host right-click menu: file management (folder), privacy screen
(shield with padlock), and drawing board (paintbrush). The new bitmaps
follow the existing #F0F0F0-background 32bpp convention and are wired
into the m_bmOnline array via LoadBitmap and SetMenuItemBitmaps, using
the same pattern as the other nested-submenu items.
