Updating login URL in new-editor.html
Generalized server php scripts so that they can accept GET requests as
well as POST requests if nothing is being changed.
Fix for resource-add.php displaying incorrect value (length) in error
message about unequal hashes
Change to util_commons.js validateBinaryData method to remove "bit and"
calculation (not sure why it was left in there).
Fix for longstanding issue where some UTF-8 text or text used to store
arbitrary bytes with characters beyond 127 had the checksum incorrectly
calculated (and so would be rejected by the server, at least with later
versions of the server).
