Import brushes from folder

- A new type of custom brush has been added, brushes from files! Basically there's a "Brushes" folder where Pixelorama can get brushes from, and, unlike the previous brushes, these are for all projects and are not saved in .pxo files. These brushes get loaded on the _ready() method of Main.gd, and are ignored by Godot.
- There are now 2 containers for the two types of custom brushes. The main pixel brush is with the brushes from files.
- Fixed bug where, if you had selected a custom "project" brush and loaded a .pxo file, the brush would still be selected, causing potential problems
- Fixed bug where you could save a project brush that was completely transparent
- Fixed bug where, if you named a file, some shortcuts would be activated.
- export_presets.cfg is now ignored.
