new libdc, new dailies

[Dirk Hohndel]

Hi there,

Linus and I merged the latest libdivecomputer changes from Jef which
should fix a couple of things for the Hollis DG03 and add support for the
Aqualung i450T and i550. This brings in a few changes to the Atom parser.
Would be nice if people with access to divecomputers that use that backend
(or even better, one of the three dive computer mentioned) could give this
a quick test.

I triggered new daily builds for all the relevant platforms

Thanks
