Added macros to iterate over matrix

This avoids having to write double for-loops again and again.

- 'matrix_loop' just replaces the loops and gives access to the indices i
and j
- 'matrix_foreach' initializes a double pointer to the current element
- 'matrix_foreach_idx' is combination of the two above

All for-loops that simply iterate over a matrix have been replaced.
