Partial push of Josh's configure-dive-computer GSoC project

[Thiago Macieira]

Hi everyone

This is just to let you know that I've pushed a portion of Josh's work and 
signed off on it to 
	https://github.com/thiagomacieira/subsurface/tree/joshua-gsoc

This contains commits I've felt so far to be in good shape. Though, Dirk, 
please don't merge them yet, we've got more coming.

The next commit in the series contains a bug I'd like Josh to fix (Josh: 
comment left on GitHub) and then I should be able to push 20 more commits.
