hashmap: size hashmap bucket array dynamically
Instead of fixing the hashmap bucket array to 127 entries dynamically size it, starting with a smaller one of 31. As soon as a fill level of 75% is reached, quadruple the size, and so on. This should siginficantly optimize the lookup time in large tables (from O(n) back to O(1)), and save memory on smaller tables (which most are).
