Short Description: SCT: keyboard accelerators on "Save Model" ops; other chgs.
Bug Number: 4073
Release notes (y/n): Yes
For Release Nums: 5.3

Gnats 4073: SCT doesn't handle some keyboard accelerator.

We used this opportunity to straighten out a couple other keyboard
accelerator assignments.

-------------------
QtSCT/SctDialog.cpp
-------------------

ADDED Keyboard Accelerators:

  "Ctrl+S"        :  File >> Save Model
  "Ctrl+Shift+S"  :  File >> Save Model As ...
  "Ctrl+F"        :  View >> Fit Row Header Columns
  "Ctrl+G"        :  View >> Grow Columns to Data

  _saveModelAction      -> setAccel (QKeySequence (tr ("Ctrl+S")));
  _saveModelAsAction    -> setAccel (QKeySequence (tr ("Ctrl+Shift+S")));
  _fitRowHeadersAction  -> setAccel (QKeySequence (tr ("Ctrl+F")));
  _growColsToDataAction -> setAccel (QKeySequence (tr ("Ctrl+G")));

REMOVED Keyboard Accelerators:

  "Ctrl+S"    : Edit >> Surcharge Release
  "Ctrl+G"    : Edit >> Regulation Discharge
  "Ctrl+F"    : View >> Refresh

  _setSurchargeRelAction -> setAccel (QKeySequence (tr ("Ctrl+S")));
  _setRegDischargeAction -> setAccel (QKeySequence (tr ("Ctrl+G")));
  _refreshAction         -> setAccel (QKeySequence (tr ("Ctrl+F")));

NOTE: We didn't end up putting the Ctrl+O Accelerator on "File >> 
Open Model ...".  Ctrl+O is already used for "Edit >> Set to Output",
which is an important operation.
