Remember last folder of the Save As dialog when downloading files
Remember last folder of the Save As dialog when downloading files

This is done by creating the dialog only once and holding a
reference to it in memory. When the dialog is closed, it is only
hidden instead of destroyed. So, the next time we just re-show
the dialog with the previously used directory. It is destroyed
when the parent MidoriBrowser instance is destroyed.
