Add StrEquals(), as equality checking is the most common use for strcmp().

Browse source 
This allows us to get rid of the hideous MATRIX_PATH_PART_EQUALS macro,
and prevents inconsistent usage of strcmp() (for example, !strcmp() vs
strcmp() == 0).

StrEquals() also has sensible behavior for dealing with NULL strings (it
doesn't just segfault like strcmp()).
