Bug fix: Info sidebar width in GTK3

In bar_size_allocate() the width obained is the allocated width. In GTK2
this is the actual width. In GTK3 it is the *minimum* width. This
results in the info sidebar being able to increase, but not decrease.
There does not seem to be a way in GTK3 to get the actual width of a
widget. For GTK3 the only way is to disable it. The width of the sidebar
is therefore not preserved across restarts.
