fixes multi-dimesional array initilization bug

Solves the bug described in issue #117

new [][2][3] = { //default values };
The compiler does not create enough room for the indirection tables and
hence adjust_indirectiontables overwrites the default values leaving the
array wrongly initilized.

Adds a generic code which works for any n-dimensional arrays (n = 1,
2,3,4,5... infinity). The code fixes the issue for any dimension but the
number of dimensions is limited to 4 (sDIMEN_MAX). A review of this code
won't be required if the limit is increased in the future.
