Small fixes, changes and feature requests for October

@razzziel

Before 3.3.0, if you changed scenes, the dialogue box would continuously stay on screen. After 3.3.0, this was no longer the case and the dialogue will “blink in and out”, which disrupts the visual flow and is very distracting when playing (to me).

This is now fixed in 3.4.0 (it shouldn’t do it by default anymore), but I also added new ways to control all those behaviours

screen shake feature

There’s now a whole animations feature which includes built-in screenshake.
