URGENT : Fixing 1.5 transactions stalling issues + fixing sync issues

1.5 Suffers from LTC's low amount of transactions.
DOGE requires huge and vast amount of transactions to be sent per block.
Currently the DOGE 1.5 is 1:1 to LTC base which does not allow it to
have >80 transactions mined in a block. Bigger pools send ~50-60
transactions per block. Total of all pools are sending >250 transactions
per block and the network can accept max up to 100 transactions.
Please accept this PR and make an organized update with all the pools
in order to resolve DOGE's issues once and for all!
Also ban 1.4 from syncing because its causing 1.5 sync lag due to flood of 1.4 clients stuck on the old fork. ( screenshot single node running 1024 maxconnections http://i.imgur.com/7qyEjz8.png )
