Merging a bunch of separately developed functions:
...
fix16_mul, fix16_div, fix16_sqrt.
They are faster & more accurate than the previous versions.
Closes issue #13 .
Includes unittests for the functions in question, runnable
by typing 'make' in the unittests folder.

Added int64.h which performs 64-bit calculations using 32-bit operations, this means that the FIXMATH_NO_64BIT macro can now be used to enable these operations on compilers without 64-bit support, note that some of these operations are slower than the built-in gcc ones (though some are faster too).
...
sqrt can now be compiled without 64-bit compiler support.
All remaining functions which aren't supported in 32-bit are now disabled when the FIXMATH_NO_64BIT macro is enable which should stop any compiler errors on compilers where 64-bit isn't supported.
