Fixes/Enhancements

- Removed bar data from exported drawings, which should reduce the file size of exported drawings. (Make sure to back up any drawing files before running the new version!)
- Drawings can now be deleted through each’s right click context menu.
- Added the new ‘hotkey’ method, which will execute the given method or function when the key command is pressed.
- Non-fixed callbacks no longer need to be placed in the API class.
