Improve deco handling and add NDL support

Browse source 
This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.

This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).

If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.
