Subject: [PATCH] dashboard: o/s shortcuts to open a script and save via a file
 dialog

Two new dashboard keys, mirroring the existing x=export: 'o' opens a file
picker to run a .essim script (-> source <path>), 's' opens a file picker to
write a system snapshot (-> save <path>, only when a system is loaded). Both
use OpenFileDialog with a per-key persisted last directory; the global
CatchEvent already yields to the file-dialog modal while it is open. Dashboard
help hints updated.
