- Replaced the static string buffer in ProcessStates with an FString.

- After doing some tests with state label scopes I had to conclude that
  using '.' both for separating sub-state-labels and scope resolution 
  identifiers does not work reliably unless all actor class names were
  prohibited from being used as state labels.  Since that is undesirable
  the only solution is to change the scope resolution operator. Fortunately 
  no WADs so far have used it so implementing such a breaking change isn't 
  a major issue. Now it uses '::', like C++ for this purpose.
- Converted Revenant, Mancubus and Pain Elemental to DECORATE.
