Sort improvements

[dieggsy]

It would be nice to be able to override previous 'sort' options with latter ones like so:

exa --group-directories-first --sort=extension --sort=created

This would sort by created, rather than printing the message Option 'sort' given more than once.. This makes defining aliases with a default sort and overriding that sort easier.

Also, is there planned support for "short" sort options (e.g. -X in gnu ls to sort by extension)?

Hi! Allowing multiple arguments is being tracked in #125. The aliases case is something I completely missed, which is why I didn't see it as a big deal. The fix will probably be to change the options-parsing library to one that supports it.

Maybe! I'll leave this issue open for now.
