#941 gtk3-3 gtk-v1.ui is very broken

[Kevin R. Bulgrien]

Window position saving in the gtk3-3 gtk-v1.ui is extremely disfunctional. Whereas recent issues in the gtk2 version was minimal and only impacted the bars, it seems as if almost no window positions saves in gtk3-3 take.

Furthermore, the inventory UI column is out of whack. The columns for the inventory are blown out too wide and don't fit tight around the icon (i.e. wielded, unweilded, cursed, etc.). This makes it hard to get a reasonably sized map and dialog column.

The gtk-v1.ui is an important layout. It emulates the original gtk-v1 client layout and its creation was the primary motivator for converting the gtk-v2 client to use glade. IMO, it should always be tested when .ui changes are made.
