Removed where T : new()

[CreepyGnome]

Removed where T : new() from the ParseArguments<T> factory method as it shouldn't be required if convention is followed of only mutable classes required a default constructor, and immutable classes are supported and do not have this requirement, so the new() restriction is blocking immutable classes which should typically not have a default constructor.

This resolves #310
