Sector System Beta Update

[p]This update adds the following...[/p]

1. [p]Fixed an issue with the seed value always making the primary and secondary missions the same when both are set to "Random All". This will almost certainly make any Mission Codes previous to this update create a slightly different mission.[/p]
2. [p]Minor tweaks to helicopter sling load A.I.[/p]
3. [p]Fixed a possible bug when using the dedicated "Attach Sling Load" control which would not actually attach the sling load! ːsteammockingː[/p]
