Some changes that can increase efficiency of clstm algorithm. Also bug with composer's inability to use model during composing was solved.

But using such heavy model in composing still questionable due to low performance compared with it's weight (maybe it can be useful on some types of data and with small horizon but I can't say exactly). Maybe we can refactor model structure, advices are welcome.

* release 0.6.2
