Lassi Hämäläinen e9e87b8bd9 Add missing #includes to header files
- Multiple header files where missing #includes to other headers that
  where used in the header. Correct header was included in correct
  order in source files which caused everything to compile.
- Added missing #includes so header files correctly include all their
  dependencies and fixes problems with IDEs being unable to parse
  headers correctly due to missing symbols
