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.
Cleaned up regexes used in register-dataset.cgi to support arbitrary numbers of elements for keywords. Cleaned up regexes for state selection, to omit default values. Added debug as a GET parameter, so a page can be debugged by appending `&debug=1'. Committed latest changes to file processing, to allow files to be deleted after returning to the entry page from confirmation or processing errors. Seperated out entryForm.js from entryForm.tmpl to simplify debugging.
