RiverWare 5.1 (Development, 2-10-2009) Slot Column Label Editing

Column Label Editing (by the user) is supported on TableSlots (including 
Table Series Slots) and on AggSeries Slots for both:

   (1) Slots on Data Objects
   (2) Slots with this Slot Attribute: UserSettableColLabelsBit

The latter is currently set on these two Engineering Object slots:

  WaterUser: irrAreaByCrop ("Irrigated Area by Crop")
  WaterUser: ETRateByCrop ("Evapotranspiration Rate by Crop")


Multiple-line labels are NOT supported.  Including a "new line" character
code (i.e. either "<br>" or "\n") doesn't currently work.  But that could
be made to work with a minor change in Q3GUI/RowColLabelEditor.cpp.

A bug related to supporting programmatically set Multiple-line labels 
HAS BEEN addressed: http://cadswes2.colorado.edu/~philw/2008/bugs/4619/

Request was for:
SlopePowerReservoir

  partBWTable ("Partition BW Table", 1,3),
  partFlowParam ("Partition Flow Parameters", 1, FLOW, NOUNITS, "PFP"),.

But check if also for:
  partProfileCoefTable ("Partition Profile Coef Table", 1,5),
  partBWElev ("Partition BW Elevation", 1, LENGTH),

// Weighting Coefficient slots
TableSlotProxy numParts;
TableSlotProxy partProfileCoefTable;
TableSlotProxy partBWTable;
AggSeriesSlotProxy partFlowParam;
TableSeriesSlotProxy partBWElev;

Compare To:

   // Irrigation Acreage and Evapotranspiration slots
   irrAreaByCrop("Irrigated Area by Crop", 1, AREA, NOUNITS, "",
                 Slot::AttributeBits(Slot::SimObjSlotBit |
                                     Slot::UserSettableColLabelsBit)),
   ETRateByCrop("Evapotranspiration Rate by Crop", 1, VELOCITY, NOUNITS, "",
                 Slot::AttributeBits(Slot::SimObjSlotBit |
                                     Slot::UserSettableColLabelsBit)),

   // irr_acrg_et_rates
   AggSeriesSlotProxy irrAreaByCrop;
   AggSeriesSlotProxy ETRateByCrop;
