[FR/Proposal] Per-Model Default Sort

[AAllport]

Proposal to add $sortableDefault to the model that will be used when sortable() $defaultParameters is passed null. This would override columnsortable.default_first_column

$sortableDefault would follow the same format as $defaultParameters

Happy to write the code myself!

Hey @AAllport if it makes sense to you sure go ahead; please make sure you add proper tests and readme.

Yeah, there are a few times that I've overridden the sortable function, that in tern called the vendor provided one with some default's. Makes sense where you want to explicitly define the defaults for things displayed in the user, but no in tasks, If that makes any sense.

Will try to get this sorted (pun intended) in the next few weeks!
