floating mm & dt unbuildable in 93

[knorke]

(maybe other buildings too, though some work)

changing
maxwaterdepth=0;
to
maxwaterdepth=1000;
made arm_floating_metal_maker buildable again

[Silentwings]

fixed on trac (for ba) - [969] and [972]. badly set maxwaterdepth can just be removed.

[Jools]

These are now fixed in svn. There were many affected units, such as floating metal makers, dt:s, llt:s, flak guns, seaplane factories.

I put maxwaterdepth to 1000. There are no maps that have deeper sea than that right?

[Forboding Angel]

Yes, there are. Use 10000 just cause.

[Jools]

Better just remove that tag then. I thought it would be later easier to revert changes if there already was a tag there.
