[web2py] Link button text in smartgrid

[Jim Steil]

I updated to latest trunk this morning and am seeing additional text in 
the buttons for linked tables.  Is there a way to disable this?  I liked 
how I could just set the _plural for the table before to set the text 
that I wanted to appear.  Now it appears to be appending 'for 
linked_table_linking_id_field_name' to the _plural for the table.  
Really hoping I can get rid of this....
