Prevent reserved field name when adding a field via form

Cc: Trac Release:


Trac ignores reserved names in custom fields.

We could validate a field name is not listed in TicketSystem.reserved_field_names. The reserved_field_names property is available since Trac-0.11.3 (introduced in trac:r7769).

354                                  '(ignoring)', field['name'])
