- Added all (I think), the missing Action0 properties up to those marked as supported by Version 14 of OpenTTD.
- Major refactoring of the code dealing with Action0 to make adding new properties much simpler in the future.
- Added more units tests for the various data types used for properties among the various feature types. Found a couple of minor buglets along the way.
- This version was tested with cns.grf and a recent firs.grf. Some differences in the string encoding choices when re-encoding, but these are inconsequential (string encoding is non-unique).
