v0.3.0

This is a pretty large refactor of dataloaden that allows arbitrary types for keys and values.

This removes -slice and -key entirely, and replaces them with 3 mandatory positional arguments:

• name: The name to use when generating types and constructors
• key type: the key type as a string in the format (*[])(package.)TypeName
• value type: the key type as a string in the format (*[])(package.)TypeName

Unlike before with -slice and -ptr these can be nested arbitrarily deeply, for example *[][][]*github.com/my/damn.User is now valid.

for example what used to be

dataloaden -keys int -slice github.com/vektah/dataloaden/example.User	

is now

dataloaden UserSliceLoader int []github.com/vektah/dataloaden/example.User
