A boolean array is not supported

[haviital]

This compiles:
int[] testarray = new int[5];
but this result an error:
boolean[] testarray = new boolean[5];
TypeError: Cannot convert undefined or null to object

Related error: #52

Support for this was added, but it does the dumb thing of making an actual array. I'll have to come back to this later and optimize it into a bitset.
