can't take the "sytem tray populating" dance anymore.

introducing this small hack to simply not show the system tray or adjust our size at startup until we stop getting new embeds. from that point forward it's business as usual, but this prevents all those panel relayouts, white blockynesses and what not.

the hack is slightly crude: it's hardcoded to 1500ms as being the trigger time between embeds. on my systems here it's a regualar 1000ms +-100ms between embeds, so 1500ms seems to be a nice number.

will have to see how it works for others.
