- created a BaseTheme class in theme.inc.
- added links($links = array(), $status = 0, $node = 0) to BaseTheme.
- modified all themes to extend from BaseTheme.
- modiefied theme_link() to take advantage of $theme->links().
- theme_morelink() does not require a $theme argument.

Todo
- add the other standard variables and functions to BaseTheme.
- some themes could use some more modifications.

Weird
- marvin.theme still has a story() function.
