[feature request] Last message nick completion

[tribly]

Currently nick completion is done in alphabetical order. It would be nice, if it could be done in 'last message' order, like in weechat.

Example nicklist:

demanous
demosquat
demzel_washing
dj_halloy

Example chat:

demosquat: hi
demzel_washing: <question>
demanous: morning
dj_halloy: i love halloy!

Typing de<tab> 3 times 'till the right nick is selected is quite cumbersome. It would be nicer to just hit d<tab> and have the last nick in the chat beginning with d completed.
