Increase number of include paths that can be passed through the
command line interface. The previous number, 16, is only good enough
for small projects. 128 is still an arbitrary number, but it is harder
to reach.
The code that adds an include path to the array of paths doesn't check
the lenght of the path (which can cause overflows because of strcpy).
It doesn't check if the max number of paths has been reached, either.
This patch adds error messages for such cases, giving the user more
information than before and crashing the assembly instead of
continuing and failing when it can't find a file to include.
