[ Kai Wasserbäch ]
* Synced to upstream's SVN revision 5467.
* debian/rules:
  - Added .PHONY line.
  - Resurrect -DMANUAL_REVISION, got lost somewhere and we build SVN
    revisions again.
  - Replace "-DWITH_NO_EMBEDDED_CODE=YES" with "-DWANT_CRYPTOPP=YES".
  - Change the remaining -DWITH/-DWITHOUT to the new -DWANT syntax.
* debian/control:
  - Removed DMUA, I'm a DD now.
  - Changed my e-mail address.
  - Removed unneeded relationships (no upgrades over two releases are
    supported).
  - Fix Suggests for kvirc-dbg.
  - kvirc-data: Make the "Suggests: kvirc" a Recommends, doesn't make much
    sense to install the -data package without the program.
* debian/source/local-options: Added with "unapply-patches".

* debian/kvirc-data.install: Added .notifyrc.

[ Raúl Sánchez Siles ]
* Stating the right version where kvirc-data break and replace should happen.
