Different version for log4net dependency

[reinderien]

It seems that the assembly dependency and the NuGet dependency for log4net have a conflict.

In the live NuGet 1.3 version of this package, it relies on log4net 2.x; however, the assembly itself has a hard dependency on log4net 1.2.11.0.

My workaround is to simply have log4net 1.2.11.0 in my own NuGet packages.config, and then there are no loading problems.
