Object Editor 3.6.0

What's Changed

• Scenario/savegame/landscape data visualisation by @LeftofZen in #121
• Updates to TownNames object, and viewmodel cleanup by @LeftofZen in #123
• Add source game for openloco, improve logging, fix crash by @LeftofZen in #124
• Small UI reshuffle in object viewmodel, placeholders for future content in menu, by @LeftofZen in b0a3bfd
• Fix bug meaning only 'Custom' could be written as the SourceGame type in S5Header by @LeftofZen in 166b38f
• Don't crash if an object fails to load partially or entirely from online by @LeftofZen in a0405c7

Note, the scenario/savegame/landscape viewer is view-only at the moment. Clicking save does nothing as I haven't yet implemented this functionality. Coming whenever I add it!
