Replaced injections of ILogger with ILoggerFactory

This makes resolving dependencies from the container much easier as
you cannot resolve with primitives parameters in a way that is any
more readable.

The aim of this commit is to change as little as possible with the end
result, loggers that were newed up for the parent object were given the same
name. Objects that used the base or app loggers, were given a new logger with
an appropriate name.

Also removed some unused dependencies.
