That way we get the D1 music when playing a D1 mission.
This also means we get D1 music in the menu, etc.
Therefore only keeps D1 assets loaded until non-D1 mission is selected.
Compiling net_udp.cpp with clang-3.4 crashes the compiler when parsing
a decltype that refers into the class currently being compiled. Parsing
a decltype that refers to a parent class works. Rearrange the decltype
usage to avoid referencing the current class. This makes the code
harder to read and less flexible, but prevents clang from crashing.

[Update: also affects OS X clang v6, as reported by btb: https://github.com/dxx-rebirth/dxx-rebirth/pull/35#issuecomment-73350066]
Previously, the code set itype=IT_POINT, then picked a closest point.
If the closest point was v0 or v1, itype stayed IT_POINT, otherwise it
became IT_EDGE. If itype==IT_POINT, then the function returns
(itype == IT_POINT) ? IT_NONE : itype;
=>
IT_NONE
for (dist <= rad). Otherwise, it returns IT_NONE. Short-circuit this
by returning IT_NONE without computing the distance.
Clang warns for unused static inline functions defined in a source file,
including those defined in a macro in a header, when the macro is
expanded in the source file.
Modifying a by-value temporary does not affect the underlying container,
so modifying it is almost always a bug. Require use of a by-reference
capture when modification is desired.
