IWEL: Identify Items for Active and Requested Well Controls

Browse Source 
This commit refines our understanding of IWEL items relating to well
constraints.  In particular Item 8 is the well's active control mode
as determined by the simulator from dynamic state variables.  On the
other hand, Item 16 is the constraint that is requested in the
simulation run input for prediction wells (keywords WCONINJE,
WCONPROD) while Item 50 is the requested constraint for wells
controlled by observed rates (WCONINJH, WCONHIST).

Special Note: This commit outputs the requested control mode to Item
8 and will need an update later once the simulator becomes aware of
the distinction.
