Fix for inability to edit existing comments/bugs

The ID generated for a comment or bug can have a ‘+’ in it, which is
xdmp:url-decode’d into a ‘ ‘ (space), causing some comments and bugs to
be uneditable.  Just use a map:get to obtain the ID passed in.
Enable RFEs Issue #7

Add ability to create a request for enhancement (RFE) by extending the
Bug feature of a Demo, now renamed to be “Bugs & RFEs” on the Demo
page. When creating a new Bug/RFE, select either the ‘defect’ or
‘enhancement’ Type.  This Type is also editable after the Bug/RFE has
been written.
