- Additional operator functionality added to Feed and Post

Factories
- Updated to solidity compiler 0.5.11
- Factories now all use the standard `create()` and `createSalty()` functions
- Templates now all emit an `event Initialized()`which logs the initialization parameters
- Metadata is removed from state to optimize gas
