1.0.01.000

Add Scallop Phase property; modulating it produces wavy scallops.
Add Load Texture command to File menu, so it's more obvious how to load
texture.
Allow texture file to be loaded via drag and drop from Explorer.
Add check for updates feature.
Optimize texture mapping, by copying texture from outer to inner wall.
Add option to continuously update view during spline dragging.
