v0.5.4 released! Keyword is data-protection. Many small bugfixes, but

main changes are:
- Modified marker (* character before name) goes up the project tree by
marking all parents of a modified object as modified.
- Impact management when changing an object's ID. Allows for some
refactoring to occur, while marking the impacted elements as modified,
or aven creating "altered" versions if imapcted element was only in game
source.
