Bumped versions to 0.4.0.0

Upped versions of nuget package projects

log4net dependencies have been removed before.
See also MUnique#188

Increased package version to 0.3.7

Since the last package, a lot of minor fixes have been applied, especially regarding quest messages.

Bumped version because of small but important changes

Added more extension methods for variable sized packets

Added lengths for some packets, too.

Added extension methods for IConnection to simplify packet sending

They're auto-generated and based on the xml data.
Had to slightly adapt the Type pattern for enums, so that the class is specified in their type name. That's required because these names are not used in the same class, but in extensions.
I also had to reference MUnique.OpenMU.Network, because of the IConnection interface. They were both unrelated, but if I wanted to make use of extension methods I had the following options:
  * Put the extension methods into Network and reference Network.Packets
  * Put the extension methods into Network.Packets and reference Network (-> I did this)
  * Create a new project which references both

For the sake of simplicity I've decided to run all xslt in Network.Packets.

Bumped Network.Packets nuget version to 0.3.4

Update nuget packages

Added length of ClientToServer packets since last version

fixed path

Improved Dockerfile - removed ci=true, instead call restore before

I noted this, but can't find the related issue of msbuild anymore :S
