Support for ' char in usernames in license form
Fixing the bug required three changes - html decoding the user's
fullname when it is used to compare with the license name to properly
set the "I own the rights" flag and when it is used to populate the
RightsHolder textbox when that flag is first clicked, and using double
quotes around the @authorName filed in the onclick= 'return updateData
call where the use of single quotes around that field previously
terminate the string literal early...).
