Log Message:
Update p5-Email-Simple to 1.995.

Changes:
1.995    2006-10-19
  - tentative refactoring of headers

1.992    2006-10-05

  - fix a number of bugs when setting multiple headers, which would often
    refuse to set more values than were currently present
  - added a test for prepending (rather than appending) headers; while E::S
    does not yet support this, the header behavior will be easier to replace in
    future versions, and this is a forward-looking test

1.990    2006-09-05

  - ->header('foo') returns false if there is no foo header (formerly '')
  - croak if an undef value is passed to new()

1.980    2006-08-17

  - fix _fold() to add a missing line ending [RT #20764] (Brian Cassidy)

1.970    2006-08-17

  - bring ->headers method into Email::Simple
  - ->header_names and ->header_pairs

1.96    2006-07-28

  - output headers in predictable order
