brownie 1.2.0

Added

• ethPM integration
• ProjectContract objects persist between sessions (when enabled in the config file)

Changed

• scripts.run only works when a project is loaded, supports multiple loaded projects

Fixed

• use isinstance instead of type for conversions, fixes hexstring comparison bug
• pretty printing for more objects in the console
• properly display SyntaxError in console when there is no source highlight
• improved regex statement for finding individual contracts within source files
• favor ==x.x dependencies over >=x.x <x.y, removed deps-of-deps to reduce conflicts
• delete stale compiler artifacts from build/contracts/ when contract name has changed within the same source file
