v0.1.0: First prerelease!

This first prerelease consists of the following features:

• Create, Delete, Edit, Save and Load learning worlds, elements and spaces!
• Elements and spaces can currently be placed in worlds, placing elements inside of spaces will be implemented in the next version.
• Generation of an empty but valid Moodle backup file without use of templates or other temp files.

Known bugs and issues:

• Pressing cancel on the Save or Load dialogues crashes the application
• Loaded worlds/spaces/elements sometimes don't show up immediately and a new object of the same type must be created before it shows
• Startup times can vary widely

Installation:
Windows: Please use either the Setup .exe or unpack win-unpacked into a folder of choice, then start AuthoringTool.exe
Linux: It is highly recommended to unpack linux-unpacked into a folder of your choice and then run the file authoring-tool manually, as this method is by FAR faster than the AppImage or snap packages, which are also provided for your convenience.
MacOS: Either use the .dmg file or the provided -mac.zip below.
