At least on my system floor() and log10() return double, so the other
arguments to Clamp() and ClampDn() didn't match anymore, now being float
instead of double.
I replaced the calls to log10f() and floorf() to avoid any ambiguities.
Also changed all "if (this==NULL) return;"s.
Fixes some -Wtautological-undefined-compare warnings.
Quoting Clang:
"'this' pointer cannot be null in well-defined C++ code; comparison may
be assumed to always evaluate to false"
The code used to store the world pointer as a console variable
"pwoCurrentWorld" of type INDEX (int32) - that won't work for 64bit, so
I added CShell::SetCurrentWorld() and CShell::GetCurrentWorld() and
store it as a pointer.
