Hopefully fixing the project-breaking bug (#381)

* Fixed Dependecies

I moved some scenes in the last minute. Stupid me. I hope it is fixed now.

* Revert "Fixed Dependecies"

This reverts commit 9e7bcd8.

* Auto stash before merge of "main" and "upstream/main"

* Update Changelog

To contain the changes I made during the last week.

* Revert "Auto stash before merge of "main" and "upstream/main""

This reverts commit 8e1699d.

* Add the new styles to the remaining pickers

TimelinePicker, ThemePicker, OperationPicker, GlossaryPicker. It also removes the [] around the items, except for the operation picker. I wasn't sure if it wouldn't make readability harder having three similar buttons next to each other, so I kept the [] there. 

And it adds a "Bus:" label to the AudioPicker, because I thought it would make it cleaner.

* Cleanup and Simplification of the MasterTree.gd

* Auto stash before merge of "main" and "upstream/main"

* Removing the regression

These lines just made such a mess. I'm not even sure why. But it works WAY better without them.
