Failling to register new nickname when nickname or channel name has spaces

[VelkanGk]

Since arguments are being splitted by spaces from the begining, by the time they arrive to nick.js are recognized as wrong formatted.

!nick registrer "Test User" "Test Channel"

args = {'nick','register','"Test','User"','"Test','Channel"'}

I've worked this around by merging args and replacing the correct splitting point with some characters and then splitting it again.
