May 6th, Minor Site Update

[Rennhack]

A few people complained about one specific news source "Environment News Service", which is anti-nuke.  So we removed them from our news feed on the home page.

Fixed the link to the MSDS searc engine on the MSDS page in the study section.

Fixed the search link on some older pages.
