Updated sin lut to use ~200KiB for it's table with the same accuracy, the lookup table implementation tends to run at about 33-36% of the speed of sinf on my machine (Intel T5500).
...
Fixed a bug in the sin lut code so that the results are always accurate.
Changed fixsingen tool to generate tables correctly for the new implementation.

Added fix16_exp currently using the Taylor Series algorithm off Wikipedia, if anyone can optimize this better then go ahead.
...
Modified fixtest to be a little more generic, can now easily change which function it tests.

Changed conversion functions to macros so that they can be optimized out by the compiler which should make optimized functions much more readable.
...
Implemented FIXMATH_NO_ROUNDING in all multiplication and division functions too, it should now work for all functions in the library and allow for a choice between speed and accuracy on different projects.

Fixed errors in asin/atan, where incorrect integer maths was used.
...
Added a macro (FIXMATH_NO_CACHE) to disable caching.
Added fix16_lerp8 and fix16_lerp32 (should be part of fract module really).

Changed consts such as e, pi, one to macros as suggested by mth for compiler optimization purposes.

Initial commit. Since its use in fgl and the Dingoo SDK the functions have been separated into more descriptive files/modules.
