Red Metal Theme

This is my fourth theme, quite a departure from the others. This theme is based on the Metal engine (instead of pixmap), so it is quite fast. Actually, I have found that the metal theme is slightly faster than the default gtk theme.

One problem with the Metal engine is that it hardcodes black as a color for some of the text/decorations. With the exceptions of what it hard-codes, it can be made to look quite nice.
