Fixed example tests.

* test:clean task also deletes .expected.html files
* LinesOfCode encoder can deal with tokens that have no scanner.
  Tests were added for this.
* JSON encoder load rubygems if necessary.
* NEW :loc as an alias for :lines_of_code
* NEW Scanner methods marshal_dump, marshal_load
  FIXED Tokens dumping (failed while trying to dump @scanner)
