Update changelog to note things I forgot to mention
Fixed reference to tags in add_field documentation
The spec "support/date-http" can fail on a non-english machine because
of the month name, added `locale => "en"` to fix it.
input/collectd: Correctly bitshift type values

  * Type values were not correctly bitshifted
  * Fix type_map and get_value defs
  * Fix some whitespace issues
input/collectd: Implement signature verification

  This code adds signature verification to the collectd input. It uses
  the same authentication file as collectd does and reloads the file if
  it has a newer mtime. When the signature on the packet doesn't match,
  the packet is not processed.
input/collectd: Implement packet decryption

  * Closes LOGSTASH-1640
  * Altered the main loop
    * Should be faster because we don't loop through every byte
    * Makes decrypting the packet easy
  * Added several constants so we don't initialize certain variables
    every time
  * Added rspec tests
