Some Bitparking changes.

We've added DGM:

• Fee: 1.5%
• Pay Tx Reward: No
• Variable difficulty: user defined
• Local work: stratum
• Pay Orphans: yes
• ASIC Ready: yes
• Merged Mining: yes

The PPS side of things has changed the fee to 3.5% for bitcoin and kept it at 2.5% for altcoins. The bitcoin fee is gradually increasing to 5% however so you might as well just put that. PPS bad luck streaks have been a killer.
