Rewriting the error handling in planner.c

Printf is not a way to issue warnings and errors. This is a very late
addition but seems necessary for a viable release of the planner.

This also adds one artificial limit and two warnings:

a) no dives deeper than 400m
b) warning of potentially very long calculation times for dives longer
   than 3h (180min) before the ascent and dives deeper than 150m

It also creates quite a number of new strings that need to be translated
(and marks a few existing ones for translation as well).
