A first example: GUI controls - namespace problem

[pauljurczak]

using Gtk.ShortNames, GtkReactive
sl = slider(1:11)
win = Window("Testing") |> (bx = Box(:v))
push!(bx, sl)
showall(win)

produces UndefVarError: showall not defined. This example works fine with using Gtk added.

It's already fixed in the docs source, but it looks like the hosted docs haven't been updating due to this line. Should be fixed once #81 merges and there's time for the docs to rebuild.
