Waitscreen while loading

[kris10ansn]

This is my first time doing a pull request, ever 😅

This commit makes the wait screen show up while loading. When the level is done loading the screen stays for however many seconds there are left. If the loading takes more than two seconds it should disappear instantly.

Now there are some caveats:

• I modified the createPlayerProgressLayer function to rather take player and levelname than the whole level as an argument (the level isn't available before loading).
• I created a createDummyDashboardLayer for the waitscreen as the createDashboardLayer needs access to the level to get ahold of the leveltimer. This could be done in other ways too, like adding the dashboard after the level is loaded. This would not be as seemless unless you are hosting the game on your own computer with little to no loading time.. There are probably better ways to do this, but i simply didn't have time to explore it.
