Added scala project files.
First integration of Scala builders.
Migrate code to scala...
Use options instead of null.
Refactoring - moved JSONObject towards data objects to be able to change the concrete implementation - after this has been done I can maybe push back the creation to the loading code.
Added settings to use tabs (instead of spaces).
Works - but parsing of the JSON is really slow (and don't know why).
Moved CategoryItem to Scala :-)
Just some very small code clean-up.
Proof that play-json doesn't work on android.
Proof that json4s works on android.
Migrated parsing of a Tour to json4s.
Migrated parsing of a TourList to json4s.
Avoid unnecessary cast.
Migrated parsing of CategoryItem to json4s (still buggy).
Fixed problem of recursive parsing of the CategoryItem child's.
Converted ImageLoaderTask to scala - needs workaround for scala compiler problem related to typed params array.
Found a better workaround for https://issues.scala-lang.org/browse/SI-1459.
Migrated WebLoaderTask to scala.
Simplified WebLoaderTask.
