Add support for aliases and boolean type

- aliases are now generated as new types or arrays (if length > 0)
- bool is recognized as a boolean type and generated as Go bool
- comment with original JSON is now prepended for each object type
- interface Services is now generated at the top of the file to provide
  overview of what RPC services does the current module consists of
- dump services now correctly return slice of the particular details type
