/*
Dev note: I had to re-design the versioncheck page to make the code less cluttered. 
As a result, the changes applied by Sander to make this page fit into the new installer 
are gone. Please do not re-introduce those changes: they were bad in the first place. 
Instead, the installer needs to be reviewed. I updated the installer a little bit to make 
sure it doesn't break entirely, however I suggest re-designing the installer without the 
OO-approach: only use OO where it makes sense and if you have no dependencies. 
This is not the case: coppermine has been built the old-school way (without OO), and there 
is little benefit in the OO-tech of the new installer. It doesn't have to be re-built from 
scratch though. 
Further discussion should be led on the dev board.
