Added BWebSettings and BPrivate::WebSettingsPrivate. Added all the wiring

necessary. The only usable effect as of yet is that favicons arrive at the
BrowserWindow. Favicons are stored in a database and are not fetched when they
alreary exist. The application is expected to try and fetch an icon for a given
url. This is currently done in BWebWindow when the URL for loading has been
initiated. Otherwise it fetches the URL upon the new ICON_RECEIVED notification
from the FrameLoaderClientHaiku. In any case it ends up at BWebWindow::IconReceived(),
so derived classes don't have to worry about the difference. In any case, via
BWebSettings, icons can also be fetched manually, like for the forthcomming
autocompletion text control.
