Subject: Made ItemContainer wrap items depending on its width again

This is instead of taking a fixed number of rows and columns. The
inventory and trade window are now resizable again.

Other smaller changes:

* Don't use bold font for the labels in the item container
* Changed "(Eq)" back to "Eq."
* Removed the ugly grid lines
