Updated to version 0.25.

Pkgsrc changes:
  - Software does not accept any version of p5-Crypt-OpenSSL-RSA anymore.

Changes since version 0.24:
===========================
 * we now only sign headers that IETF recommends for signing
 * it's now possible to "prettify" outgoing signatures, but this feature
   is not enabled by default. To enable, do a "use Mail::DKIM::TextWrap"
   in your program that signs messages. (This may change in a future
   release.)
