Enhance theme functions

Two note:

1) You should provide theme_ functions to customize the voting mechanism for users.
2) You shouldn't do format strings into the t() function if it's not i18n sensitive, like this (line 253):

 $o = t('<div id="nodevote vote">Please rate this node. 1 = worst score, 10 = best score<br/>');

The good practice is here:

 $o = '<div id="nodevote vote">'.t('Please rate this node. 1 = worst score, 10 = best score').'<br />';

(The space before "/" in <br /> is important!)

If you mind, I try to help.
Bests,
