dcrpool v1.2.0 RC3

Breaking Changes.

1. --cpuport, --d9port, --dr3port,--dr5port,--d1port and --dcr1port have been removed in favour of --minerport (#274).

2. --homedir has been renamed to --appdata in order to be consistent wih dcrd and dcrwallet (#312).

Bug Fixes.

1. Payment processing now handles dust payments by filtering them out of transactions generated by the pool. (#254)

2. Fixed a solo pool work submission related bug where valid submissions less than the pool target were being rejected. (#286)

3. Fixed a gui related bug where the gui would fail to update because the cache was not being properly updated on block connections. (#297)
