source code re-organization

[Erik Joelsson]

Hello,

It would be great if this could go in anytime soon. For my needs it 
doesn't need to be perfect from the start, we will just tweak it as we 
go. I'm currently working with the patch applied locally and have 
started adding to it, but would like to not diverge too far.
