### Build 17
- Diversified heal rate for military buildings - the bigger, the quicker.
- Improved and remodelled a lot of the buildings' animations.
- Improved and remodelled a lot of the bobs' animations.
- Improved and remodelled a lot of terrain graphics.
- Improved dedicated server functionality:
    * now runable as daemon and thus via init.d script on servers
    * added possibility to write server statistics to html files
    * added functionality to save the game on the server via chat command.
    * added functionality to set up a password for the server.
    * added functionality to set a custom message of the day (motd).
    * improved client side handling / setting up of dedicated servers.
- Improved a lot of icons and button appearence.
- Improved statistics window.
- Improved the Widelands code to use less resources.
- Improved OpenGL rendering which is now active by default.
- Improved (slightly) the computer player through use of the new
  dismantle feature.
- Replaced the old libggz based metaserver support with our own ggz
  independed solution, which brings some new features as well:
    * The metaserver is now checking whether a game is connectable
      if it is not, it sends an error message to the client to
      inform it.
    * System messages on the metaserver like global announcements
      motd changes or Error-Messages are now imported to running
      games and shown there as well.
    * The metaserver does now check whether a client is still online
      regulary and disconnects it, if it isn't.
    * If the client gets disconnected from the metaserver during a
      running game, the client is able to reconnect silently.
    * Games can now have more than 7 connected clients
    * The Version of Widelands used in a game is now shown as hover text
      in the game list. If a game is connectable, but uses a different
      version, a "?" icon is shown to visualise that difference.
