Impove look and feel of Mesh/Texture selection dialog.

[i-make-robots]

Textures should show thumbnails.

Meshes could show a thumbnail. How they would be generated is a great question.

Detail and thumbnail views?

Should the Load button become a Add button?

[i-make-robots]

The "load new" could be below the list, next to "clear".

"clear" is mislabelled. It sounds like a verb. I'm not clearing out all the existing assets! It should be "none"

a4607d5 added bevel border to dialogs, makes it more clear there is a button.

a4607d5 clear buttons now look like every other toolbar button. consistency ftw!
