get_units() returns the current unit preference, thus it
belongs in prefs.c rather than gtk-gui.c

- MOD: Maximum Operation Depth based on a configurable limit
- EAD: Equivalent Air Depth considering N2 and (!) O2 narcotic
- END: Equivalent Nitrogen (Narcotic) Depth considering just N2 narcotic
(ignoring O2)
- EADD: Equivalent Air Density Depth
Please note that some people and even diving organisations have opposite
definitions for EAD and END. Considering A stands for Air, lets choose the
above. And considering N for Nitrogen it also fits in this scheme.
This patch moves N2_IN_AIR from deco.c to dive.h as this is already used
in several places and might be useful for future use also. It also
respecifies N2_IN_AIR to a more correct value of 78,084%, the former one
also included all other gases than oxygen appearing in air. If someone
needs to use the former value it would be more correct to use 1-O2_IN_AIR
instead.

.. and add the usual logic to not save the default values.
This also simplifies the initial system-specific setup of both of these:
since we have defaults for all the preferences that get set up at
startup, we can just initialize those defaults to the system-specific
fonts then and there.

Testing the new "don't even bother saving default values" showed that the
default values for the deco gradient factors were undefined.
Or rather, they were over-defined.
We had defaults for the UI (30 and 75 for GFlow/GFhigh respectively - the
config ones are in percent), *and* we had defaults in deco.c for the deco
code itself (0.35 and 0.75 respectively - in deco.c they are represented
as fractions, not percent).
And if the config entries had never been written, and were assumed to be
the defaults, the UI code thought the defaults were 30/75, but they had
never been *set* to those defaults, so actual default calculations
silently used the 35/75 in deco.c, which is very confusing (you could go
to the preferences page, see the 30/75 there, and it would not actually
match th evalues used for computation).
Of course, with an old config file that saves even default entries, you'd
never see that if you ever changed anything in the preferences, because
you'd always have explicit gflow/high values. But now it's much easier to
see the conflicting default values.
Fix it by just always using the UI defaults (or set values) to set the
actual deco values.

This does the "don't save defaults" for numeric values too.
Also, move the preferences loading/saving to a new "prefs.c" file.
