improve some Hash Functions

improve some hash functions

simplfy and cleanup

WIP

[commy2]

In 1.55dev
L38 to L47 can be replaced with:

private _keys = _array apply {_x select 0};
private _values = _array apply {_x select 1};

The suggested code changes result in an error being displayed even as the game is started.

Fix the errors and run the CBA hash unit tests and make sure it works.

This doesn't look right.

Still fails two unit tests

This is what I meant previously. The hash functions are not usable in scheduled environment currently.
