documenting new settings of 1.4.0 release on the man page:
downloadspath, statusfont, urlboxfonts and completionfonts
Fix keybinding not being available to override through configuration settings.

In the function changemapping() the linked list of keybindings is traversed in
a way the last element of the list (tail) wont be processed to rebind.
The loop iterates over all elements of the linked list until an element
which has none _next_ to it, ie: the last one, efectibly skipping the last element
in the list.

The changes fix this by iterating over all elements until finding a NULL element.
