perf(l2): Nodes slides in smoothly, Diagnostics opens in half the time

Browse Source 
Rows still to build wait while a screen slides in, so its frames aren't
a fill budget apart (Nodes: 12 frames of 24 ms instead of 7 of 33, up to
65). The crash dump in flash is read at boot, not on the first
Diagnostics (build 54 -> 20 ms). The perf tools time Nodes too.
