Subject: [PATCH] Look for caja extentions at $CAJA_EXTENTSION_DIRS

CAJA_EXTENSION_DIRS is a list of paths where caja extensions are
looked for. It is needed for distributions like NixOS that do not
install all extensions in the same directory. In NixOS each package is
installed in a self contained directory.
