Added an error handler to pool initialization methods so we don't get chipered error messages any more in-case a pool can't initialize.
Pools whom can't be initialized will be not added to PoolManager's internal storage now.
Added scrypt-og support.
Added sha1, qubit, nist5 and fresh support.
Merge branch 'develop' of github.com:CoiniumServ/CoiniumServ into develop
