Interact Menu - Simplify fnc_renderActionPoints

[Dystopian]

When merged this pull request will:

• title.

To understand how inline function _fnc_renderNearbyActions works I had to simplify it a little. Changes:

• use continue to decrease loop nesting depth;
• replace _numInteractions (int) with _hasInteractions (bool) because number is not used;
• fix _classActions = _namespace getVariable typeOf _target doesn't have default value;
• some small code optimizations.

It's better to view changes in IDE than here in GitHub.
