Fixes for clientconfig (debug/timeout)

This patch fixes the following issues with the client configuration (meridian.ini)

1) It was impossible to get the debug console to show up even on debug-builds, because it was disabled fully in code. The client writes its debug text to this console-window, which usually should show up if you set "Debug=1" in the [Special] section of your meridian.ini. This debug-window is supposed to work unless the binary was built with FINAL=1,  which is the supposed flag for distributing it afterwards. (Instead of RELEASE=1 or DEBUG=1)

2) This patch sets the default logoff timeout from 20 minutes to 1440 minutes (1 day). Please note that there is already a configvalue for this in meridian.ini, it's "Timeout=20" in section [Miscellaneous]. So this will not automatically change for users, they have to change their config value. Also the code was modified to read this timeout value also for builds created with FINAL=1, which otherwise would ignore it.

PS: I have not increased client buildnumber with this pullrequest, because there's already one pending for the client which does, the blind-change: https://github.com/Daenks/Meridian59_103/pull/184
