Print.c : fixes problem with line height in print_tanks

A "\n" was giving 2 lines height for the layout.
Wipping it out makes unnecesary the *2 divisor.
As there may be wrapped strings in tank we need to take
account of this height. There is no need, really, to get the
height of the gasmix or gas_consumed strings, as they are
"semi-fixed" size, but under some locales and imperial units they
could be wrapped too.

statistics.c: Added missing translation of "<unit>/min"

"<unit>/min" should be OK for most Latin languages, but for Cyrillic
we have to translate "min" as well.

statistics.c: Fix a potential compiler bug triggered in gcc 3.4.5

This may look as a simple formatting change and won't make much sense
to the C programmer. It is an actual bug fix in Subsurface for the
target compiler, since it introduces bogus instructions.

The "month" variable ends up being incremented up to 72 for a single
"month++" call (if inside offset brackets).

Remove substitute icons for Import and Download

Apparently at least in Unity on Ubuntu 12.10 using those icons causes the
default Menu text to be displayed (Back instead of Import).

Planner: fix wait time calculations

The problem is that when we reach the gas change depth and compute the
stop time, no gas change event is created yet but time_at_last_depth tries
to determine the gas for the stop from events.

So instead we pass o2 and he as parameters of that function and calculate
the wait time based on that information.
