The addition of the erase blend mode from #1117 resulted in loading pxo files from v1.0-v1.0.3 to have incorrect blend modes in their layers, if they are set to anything below normal, because the values of the `BaseLayer.BlendModes` enumerator changed.

The shader has more options than just brightness and contrast though, but I didn't know how else to name the effect. "Adjust Brightness/Contrast" makes it immediately obvious as to what the effect is about.
Pixelize makes the image pixelated, and Palettize maps the color of the input to the nearest color in the selected palette. Useful for limiting color in pixel art and for artistic effects.
Allows users to change project name and add custom user data. I was not sure where to put this, so I put it under the Edit menu. It might be a good idea to add a new "Project" menu in the future, and perhaps Scale Image, Resize Canvas and Crop to Content/Selection could be placed there, as they always affect the entire project.
The preferences code only handles the UI related stuff, while the Themes autoload is now solely responsible for theme adding, removing and changing. This makes it possible to handle themes without having the preferences dialog be in the middle.
I had to disable it, because for some reason having it be enabled by default does not seem to be working. This may be a good idea anyway, as many people will not need this feature, and having this enabled affects performance.
This commit also allows for changing project setting related options in the preferences to also work when running Pixelorama inside Godot.
