[WIP] 3.0

[jakubvano]

Working towards #428

Already implemented features:

• multitons
• thread safety
  • new api is thread safe by default)
• type inference
  • during registration & resolution
• missing dependency handling
  • failable stuff throws
  • optionals are handled almost transparently, as we are used to in Swift
  • we can now check missing dependencies on bootstrap (instead of usage)
• duplicate registrations
  • duplicates (overrides) are not allowed by default, detected on bootstrap
• type forwarding declarations are type safe
• scopes are completely decoupled from resolver, and are the only source of mutable state
• 2.0 api is rebuilt on new core
  • only breaking change should be custom scope handling
  • basic support for usage of 3.0 features from 2.0 codebase
• drafted support for instance retrieval / auto injection
