[Client] Let us sort our runepages

Disclaimer: I wasn't sure what sub-board to put this under, so apologies if it's in the wrong one.

Basically, remember how in the old runes/masteries system you were able to drag your mastery pages around to reorder them however you like? I would like a similar feature for the current runepages. It's not like a super necessary thing but it'd just be nice to be able to do.
