Add support for ".dae" (and others) to filepicker load filter.

* Brought llfilepicker.{cpp,h} up to speed with V3 by adding
  FFLOAD_MODEL, FFLOAD_COLLADA, FFLOAD_SCRIPT, FFLOAD_DICTIONARY
  However, note that we used FFLOAD_LSL, so I renamed their
  FFLOAD_SCRIPT to FFLOAD_LSL and kept our way of filtering.
* Fixed the filter token that is sent to the plugin for
  collada (from "dae" to "collada").
