Sorting sections in the summary

[funkyfuture]

hello there, i may be over-using this extension by returning other names than "Members" and "Attributes" from a autodocsumm-grouper handler. the order of sections within a summary is then determined by the one in which the members were evaluated. would you be interested to include an option for sorting these sections? i suppose the most flexible would be to accept either None (default) for no sorting or a callable that is then used for the key-parameter of the sorting.

thanks again @funkyfuture! I just made a new release (0.2.12) that implements the new config value from #93
