Kaspad v0.12.0 - Hard Fork

This version contains a hard fork at DAA score 14687583 (estimated to be on 28/04 16:38 UTC). Upgrade is mandatory, and everyone who doesn't upgrade will be split off the network.
The main focus of the hard fork is to address the issue of deep side chains that spam the network. After the hard fork is activated such side chains will be ignored unless they win the block race and have more blue work than the rest of the network.
