Merging Perl changes into detokenization branch. Removes usage of tokens from all Perl and Perl Template Toolkit files, instead using pure Java .property files to manage settings. Basic path for eliminating .cfg files from Perl, and skin.config files from Java side. Backported changes from 1.8.1RC1 release.
Added login status block. Reverted hardcoded path to proper tokens.
Fixed Firefox display bug due to more mixed HTML 4.01 / XHTML content
Modified all header and footer calls to be skin specific: in the NCEAS skin, skip rendering the header and footer IFRAME elements, otherwise continue as normal.
