Now the dive profile plot *really* needs some units. The pressure is
just a random line otherwise.

If given multiple dives at the same time, just de-dup the dives. This
happens when you've dumped the whole dive-computer several times, and
some dives show up in multiple dumps.
When de-duping, try to avoid dropping data. So if one dive has notes
attached to it, and the other one does not, pick the notes from the dive
that does have them. Obvious stuff like that.
The sample merge is also written so that it should be possible to merge
two dives. Which we don't actually do yet.

This just generates another xml file. Don't get me wrong: I still don't
like xml, but this way we can save in the same format we load things
from. Except the save-format is a *lot* cleaner than the abortion that
is Suunto or libdivecomputer xml.
Don't bother with some crazy xml library crap for saving. Just do it!

The only thing you can do with that thing is screw things up (like
libdivecomputer did). There's no value in tracking the "filler" gas,
since you can always just calculate it from the gases that actually
matter.
So just track Oxygen and Helium - and make sure they have sane values.

The suunto xml is just completely crazy. What's the helium percentage
companion to "o2pct"? Would it be "hepct"? No. It's "hepct_0".
Ok, so they didn't number the first o2pct, which could be seen as sane:
that's the only mix value that should always exist. And they clearly
started their indexing with 0. So with multiple mixes, you'd then
expect "o2pct_1" and "hepct_1", right?
Wrong! Because XML people are crazy, the second O2 mix percentage is
obviously "o2pct_2". So the O2 percentages are one-based, with an
implicit one. But the He percentages are zero-based with an explicit
zero. So the second mix is "o2pct_2" and "hepct_1".
I'd like to ask what drugs Suunto people are on, but hey, it's a Finnish
company. No need to ask. Vodka explains everything. LOTS AND LOTS OF
VODKA.
In comparison, the libdivecomputer output is nice and sane, and uses a
'gasmix' node. Of course, now we have so many different XML nesting
nodes to check that I just made it an array of different noces. That
also allows me to mark the suunto case, so that we only do the "check
for crazy alcoholic xml entries" when it's a suunto file.
The "type of file" thing is probably a good idea for deciding on default
units too. Some day.

I'm going to add a menu to import (and eventually export) dives, and so
we'd like to be able to start out with no dives at all. Right now we
croak if that happens - it's not like the code has been written with
actual end users in mind.
So start cleaning things up. First make the 'current_dive' macro work
right even for invalid dives.

The name is a string containint date, time, depth and length. So it's
useful even with nothing else going on.

The dive parser should eventually be just a part of the program, not the
whole thing. So start preparing for that.
