Implemented the forecasting steady mode points of the temperature parameters.

Main features:
- implemented the forecasting temperature parameters on steady modes;
- if there was found the invalid steady mode points and user choosed the
  continue of a programm work, execution will be continues from the next
  (below) lines after this 'if' conditions and not returned to the start
  cycle with help the 'continue' operator;
- added 'forecastValues' function in the 'src/add_functions.sci' source
  file for performing the linear forecasting (extrapolation);
- changed view of the valid plotted points ('plotInvalidArchive' function
  in the 'src/special_functions.sci' source file), when programm define the
  invalid steady mode points.

Implemented the forecasting 'tm' parameters values on steady mode. Debug version.
Also, perform the calculation the variance values of the steady mode 'tm'
parameters points.

Cleared code for defining forecasted steady mode points of the 'tm' parameters.

Main features:
- cleared code for the defining the steady mode points values of the 'tm'
  parameters;
- function 'linearForecastValues' in the 'src/special_function.sci' source
  file now return only forecasted values;

Implemented export/import of the steady mode points from/to the text file.

Main features:
- moved the MAIN CYCLE from the global namespace of the src/define_oil_characteristics.sce
  source file to the 'calcSteadyPoints' function of the src/special_functions.sci source file.
  MAIN CYCLE perform a calculation of the steady mode points;
- added to the src/in_out_functions.sci source file the function importSteadyPoints,
  that perform the import of steady mode points from the text file;
- added to the src/in_out_functions.sci source file the saveSteadyPoints function,
  that perform the export of steady mode points to the text file;
- replaced in the external functions 'return' statement to the 'abort' for
  ensuring the correct stopping the scilab evaluations;
- changed the 'str_currCalcIdentif' variable (that mean - current culculation
  identification), that stored more full information about current calculation,
  there are: 's' - sheep number, 'b' - board number, 'sl' - sectorLength,
  'ss' - sectorShift, 'ml' - modelLength, 'fi' - forecastInterval.
  Now, this variable uses in the next cases:
    1) steady mode points file name;
    2) destination out dir for the saving plotted images;
    3) text results file name and the title in the contents of this file;
  - corrected the argument list of the 'saveResToTextFile' function in the
  src/in_out_functions.sci source file, now the date and time information
  not pass in the 'strTitle' string variable, its pass externally in the
  'strDateTime' argument variable.
