Control command capture and replay widget state through UI

[gajop]

For capture, also write directly to file so infolog isn't polluted and so it's easier to extract desired commands

@Beherith
Would like some eyes on this - I'm a bit unsure with how to properly initialize these widgets so they're:

1. actually disabled as desired
2. don't cause load when disabled
3. loaded at exactly the right time (after lobby and Configuration are available, but before autologin/connect, which seems to be 1.8s usually - although it's disabled now)

Also it'd be great if you have any pointers on how to have user configuration for options like AUTO_QUIT_ON_FINISH which seem too dangerous even for devs. Always worried I don't accidentally commit it like 153619f ...

@gajop and @Beherith - can we close this ?
