Provisional revert of r93319 -- change to TOC styles without coordinated cache updates.

Definitely shows different padding with the old cached markup and new styles in FF 5 though it's not a huge difference. Haven't tested in other browsers; IE needs testing in particular as it has funky special style bits.

Recommend:
* old markup should work uncahnged with the new styles -- this avoids any transition problems
* secondarily, consider updating parser cache version to force updates .... but you'd still want to do the above for pages that have been HTTP-cached!
* test all these renderings in all supported browsers and confirm that all is well with old & new markup
