Add the ability to navigate between tables via foreign key relationships, addressing the first part of #209:

 - For the first column linked by each foreign key, display a link arrow within the table cell
 - When clicking on the link arrow, select the reference table and set the table filters to select the clicked value
 - Also uses the table cell subclass to allow the entire cell to be editable, not just the contained text (addresses #250)
