[BUGFIX] Allow Editing field creator_tool in sys_file_metadata

The filemetadata extension adds additional fields to the sys_file_metadata
table. The field creator_tool is defined in SQL and TCA, but not added to
any palette or tab. This patch adds the field to the palette with
related authoring information.
