remove trash-put support, it is too annoying

Using trash-put on a file in ~/sieve caused this to go in my syslog:
Feb 16 16:23:51 kd gvfsd-trash[812297]: *** Unsupported operation detected on trash directory
Feb 16 16:23:51 kd gvfsd-trash[812297]:   dir: /home/iank/.local/share/Trash/files, file: files, type: 4

A web search gives me no help on figuring out what that means. free
desktop has so many undocumented things, avoid it. Already had to
special case a bunch of undocumented trash-put stuff, enough is enough.
