Schedule nightly run to be at 6:10 rather than 5:10 
Occasionally, miri was't available yet. So we go with a 6:10 run to give it a chance to be installed.

Even faster mixer (#447) 
If you do an ldmia for loading lots of samples at once, the mixer uses
significantly less CPU (10% compared to previous, 19800 cycles per frame
-> 17701 cycles per frame for 32768Hz).

I've also added a really simple unit test for the `collapse` function to
at least gain some confidence in it.

Resolve stutter upon switching to dice customise screen (#442) 
1. Dealloc now uses the normal dealloc procedure.
    * Better because normalisation is quick, O(1).
    * More normalisation means inserting into the list is faster.
2. Run sfx frame during the generation of upgrades (which can take an
unbounded amount of time).

* Both of these are required to remove the stuttering.
* It sounds really weird now that it works right :/
