Editor: Dim UI when a WindowDialog is shown.

Darkens the editor on WindowDialog popup.

This adds the following new Editor settings:

- interface/dim_editor_on_dialog_popup (true) # Enable/Disable editor dimming
- interface/dim_amount (0.6) # Percentage of how much the editor will be darkened (0-1)
- interface/dim_transition_time # The duration (in seconds) of the color blending effect (0-1), 0 is instant.

Please test this thoroughly, I haven't yet seen a case where it fails to work properly but I'm sure I didn't test all
windows of the editor :P
