Clearer method to start time tracking for today

An option to automatically start tracking when opening gtimelog the first time at the day could solve the problem in a more convenient way.
So when starting the first time since virtual midnight a line:
2008-05-23 05:23: arrived
is added to the timelog.txt.

I'm not entirely convinced yet:

* What if you're a sensible person and suspend your laptop at night, without closing your session? Then you'd have gtimelog running for many days on a workspace somewhere out of your way (or minimized to the system tray).

* What if you've just started gtimelog to look at past history and do not intend to actually start working right now? Admittedly this argument would be more convincing if gtimelog *had* a better to look at past history (bug 220778) than opening draft reports in your mail client.

1. You can enter „arrived“ (the old method will not go away)
2. press Ctrl+e, delete the last line, Ctrl+r
   If you make this more often than starting the client and start to work, just set autostart_work = False in the gtimelogrc ;--)

Just going through my old unread email and found this message from November 2008 by Johan Wirén:

I like the idea.

I personally don't like this sniffing on inactivity/activity.
I woul'd like key shortcut - Ctrl + N = new day => logs 'arrived'
