gfse&minibar: select the right grammar in minibar when invoked from gfse

The grammar that the user is currently working is now the one shown initially
in minibar, instead of the first grammar in alphabetical order.
Also GFServer.hs now removes absolute paths to the grammar files on the server in error messages from GF returned to to gfse.
