Closes #4480

Wait until loader becomes stale to continue in project loader tests

Escape special characters in toolbox xml

Fix "See Inside" not showing variables

Fix issue #4431 by change 'dserver' to 'server'

I needed to update the player css because the editor side wasn't large enough to be useable.

We can't rely on refreshWorkspace always causing a toolbox update, so make sure to update the toolbox manually if it is needed.

Call updateToolbox after adding new blocks from the backpack.

Make uploaded sprites not draggable

Move blocks z-index up to match gui

Retain showBranding mode property after SET_FULL_SCREEN action is dispatched

Override the z-index for the blocks drag layer. At 1000, it will be over everything in the gui other than the navbar itself (monitors on the stage, tutorials, alerts, dropdown menus, etc.)

[develop] Hotfix/fix tests

[develop] hotfix toolbox language

Export costumes without inlined fonts for now

[master] Hotfix/toolbox language
