Replaces calls to double-precision floating point trig functions with
calls to single-precision floating point trig functions as follows:
cos() -> cosf()
sin() -> sinf()
tan() -> tanf()
acos() -> acosf()
asin() -> asinf()
atan() -> atanf()
This allows the compiler to avoid generating unnecessary instructions
that convert a float to a double and then a double back to a float.

Instead of performing three consecutive divisions, vm_vec_avg_n() now performs
one division at the start and three multiplications at the end. Recall that
multiplication is faster than division.

The routine atan2_safe() already contains a test that checks if both parameters
are zero--that is the point of the routine. Thus, there is no need for the
caller of atan2_safe() to perform that same check.

The routine vm_vec_normalize() always returns a value greater than zero.
Thus, there is no need to test its return value for values that are less
than or equal to zero.

Not only is the routine vm_fvec_matrix_interpolate() unused, it does not appear
to have been used for the duration of the project. The only reference to it
found in the history was in a removed comment. That comment indicated that it
was implemented in 1997.

Changes the file mode bits of vecmat.h and vecmat.cpp to make them consistent
with the other files under "code/math".

Overhaul hudartillery.cpp to use STL containers (removes hardcoded limits on maximum number of strike types, simultaneously active strikes, and projectiles per strike), use modular tables, allow for different shape options, and allow beams as the weapon.
