* Made BWebPage download related methods and listener member static.

* Introduced BWebPage::RequestDownload() public API (expected to run
   synchronous).
 * Added necessary wiring for "Download this link" in context menus.
 * Restarting downloads works in principle, although with some quirks.
   (Sometimes it appears the "Desktop" is being downloaded...)
