"Trim images" should be a more fitting name for this option, as it's quite common to export multiple images and the use of plural makes it more clear that this option applies to all exported images.
* Blend group layers on `DrawingAlgos.blend_layers()`
* Support group layer blending on the canvas
* Allow editing of group layer properties
* Fix issues with group layer blending in canvas, and unite common code
* Group layers can now be used as clipping masks
* Make move tool preview work on child layers
* Change OffsetImage's `blend_layers()` to support group layer blending
* Support group layer blending in the canvas preview
* Fix layer blending mode, clipping mask opacity and cel opacity not being updated automatically if the layer/cel changed is not selected
* Add a pass through blending mode to layer groups
Fingers crossed that no bugs were introduced
* Fix issue with layers that belong to pass through groups not updating their textures on the canvas automatically on undo

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.
Added missing strings to Translations.pot and fixed a few ones that were broken either because of missing periods, differences in capitalization or because of trailing newlines (the latter seems to get automatically trimmed in tooltips during runtime)
