[invalid] getUnitsForFaction() optional values aren't actually optional

[Omega]

OS: Ubuntu 12.04

As found by Wciow in the IRC earlier, getUnitsForFaction(int index, string command, int field) isn't treating the field (an integer where 0 = land and 1 = air) as optional (or at least it's not when a command has been entered). This also means there's no way to get all the units in the faction (besides two function calls), as you have to specify a field.

I believe there are no lua functions that have optional parameters, all parameters must be specified.

Oh, my bad. I didn't realize Lua doesn't support function overloading or default values. I updated the wiki to reflect the non-optional status.

Since the behaviour described here is as designed, I'll tag this as [invalid]. Please update the title and add a new post to the thread if / when the issue described here occurs again.

Also thank you for updating the documentation on this one, Omega.
