Completely remove RatDVD.

RatDVD was removed from the icon library and file associations in 2307da279e74b216681ef489f38b7e1bd22a04c2.
Remove unused variables.
Replace memset with ZeroMemory.

The ZeroMemory macro makes clear what it does compared to `memset(foo, 0, bar)`.
Get rid of duplicate defines.
Fix the C4701 warnings: Potentially uninitialized local variable "XXX" used.
Use the M_PI and M_SQRT1_2 defines instead of the direct numbers.

Also remove the M_PI fallback define; we always build with `_USE_MATH_DEFINES` defined.

TextPassThruFilter: move the classes to the header file.
Make a couple of functions constant.
Rename var for consistency.
WebServer.cpp: remove part of check that was always false.
