Updates on Finnish translation

A couple of bug fixes and new translations. I also took the fuzzy
marking from strings that look like proper translations.

[PATCH] Print.c: Modify for using  pango_layout_get_extents

Modify for use said pango function, suposes changing the way of doing things:
Before this we were moving along the cr (cairo object) and creating and closing a layout
for each line we printed. To use this func we need to create a layout (say for tanks),
and then we move along the layout getting the distance with the get_extents func.
As the layout is set and passed to the auxiliary functions  there's no need to pass some
values we were passing.

Clean a bit the positioning of  SAC, CNS and OTU which were out of the scope of the
change.

Changes to draw_table() are wider and unclear as we have to change from a fixed
number of dives (25 actually) to a variable one.  Not patched still.
