Release 1.2.0

Enhancements:

• Introduce replay option -j to jump ahead when all connections are idle.
  This can speed up replay. The statistics will not include the skipped time, but delay warnings will work as expected.
  Idea and original patch by John Lumby.

Bugfixes:

• Fix failure to parse string constants like E'\\' where the backslash before a quotation mark is backslash-quoted.
  Bug discovered by Jeff Frost.
