C3DHE

Fixed:

• some elements being not correctly placed onto terrain
• buttons in menu being not properly aligned
• help menu being not correctly displayed on 21:9 monitors
• trees looking like giant spikes :)

New features:

• tracks can now be loaded directly from TRK files (massive thanks to wurunduk)
• Editor does not use heightmaps anymore, which means you can set much higher elevations (more than 2000%)
• shortcut for diselecting highlighted object in build mode [Alt]
