LightBurn 0.7.03 released - Auto save, Ruida dot mode, Distribute, and a lot of bug fixes

This version primarily addresses a lot of bugs and small usability tweaks, but there are few new features we'd like to call out:

Auto-save: Every 2 minutes, LightBurn will save a backup copy of whatever you're working on.  If it's an existing file, the backup will be saved next to the original. If it's a new file, it'll be "AutoSave_xxx.lbrn" in your documents folder. If LightBurn crashes, these files should contain a very recent version of your work, and save you some headaches. We'll be making the auto-save interval editable in the near future.

Distribute: Select a number of items and you can distribute them evenly across your page, vertically or horizontally, either by making their centers an equal distance apart, or given them equal spacing between them.

Move to XY: The move window now has a numeric entry box that will let you move the laser to a user-entered absolute location.

UI Cleanup: We've cleaned up the UI, folding a number of the related buttons together into drop-button menus. This makes it easier to use the software on laptops or smaller displays where space is tight.

Language: Language files are now included in Mac and Linux versions, and your language preference is remembered.

Dot Mode: Ruida controllers now support Dot Mode in the cut settings window. We prefer the smoother motion of perforation mode, but for some materials, dot mode is ideal.
