Work in progress on better download management...

* Allow to specify the downloads folder in the General settings page.
 * Added necessary wiring.
 * The listener notification was not synchronous anymore because of mixed
   up default function params in BWebPage.
 * Added temporary debug output to WebDownloadPrivate.cpp... the restarting
   downloads code path needs testing yet.
