wp_xxyyzz c87afdcdec fpspreadsheet: Redo handling for formulas:

- Allow processing of string formulas (conversion to/from rpn formulas, calculation). 
- Drop cell ContentType cctRPNFormula. 
- Drop field RPNFormulaValue of TCell record. 
- Remove all fekXXXX declarations for sheet functions. Function is specified by name now.
- Complete registration mechanism for user-defined formulas.
Adapt all demos
Test cases working
This commit does not yet support: shared formulas, formulas in ods.

demo_recursive_calc.lpi

fpspreadsheet: Clean-up of demos (sometimes the default built mode was lost). Add some more overloaded methods to TsWorksheet having the cell as an argument instead of row/col index.

demo_virtualmode_read.lpr

fpspreadsheet: Implement virtual reading mode for biff8 and biff5 (activated by workbook option boVirtualMode when reading). Add demo_virtualmode_read. Update speed test (factor 2 faster than standard mode, main advantage: no significant memory usage)

demo_write_formatting.pas

fpspreadsheet: Rename test_* projects in folder examples/other to demo_*. Remove dependence on laz_fpspreadsheet package for easier testing, use unit directory for compiled files. Add readme.txt for this folder.

financemath.pas

fpspreadsheet: Add interest rate calculation to complete financial functions supported by fpspreadsheet. Extract financial stuff into separate unit "financemath.pas" which will be proposed as a fpc feature request.

This folder contains various demo applications:

- demo_formula_func: shows how a user-provided function can be registered in
  fpspreadsheet for usage in rpn formulas. The example covers some financial
  functions.
  
- demo_recursive_calc: demonstrates recursive calculation of formulas. All
  formulas in this demo depend on the result of the formula in the next cell,
  except for the last cell. When the formula in the first cell is calculated
  recursive calculation of the other cells is requested.
  
- demo_virtualmode_writing: demonstrates how the virtual mode of the workbook
  can be used to create huge spreadsheet files.
  
- demo_virtualmode_reading: demonstrates how the virtual mode of the workbook
  can be used to read huge spreadsheet files. Requires the file written by
  demo_virtualmode_writing.
  
- demo_write_formatting: shows some simple cell formatting

- demo_write_formula: shows some rpn formulas
