c36a5e80ce fpspreadsheet: Building a number format list which allows to drop most of the restrictions of the previous versions like number of decimal places. New number format "nfCustom" which passes the format string directly to the file.

c174566e55 fpspreadsheet: Some refinements with color handling: 
- Add some more colors to the default palette, remove the duplicate base colors
- Introduce type TsColorvalue for the rgb color values
- At init, automatically convert big-endian color values to little-endian
- Add TsWorkbook.SetColorValue to replace a palette color
- Add testing of random palette to colortests
- Add color test for BIFF2 (font only, because background color cannot be changed by design)

27498ff548 + Add support for more/easier RPN formulas in XLS 
- Allow relative cell references in RPN formulas
- Simplify generation of RPN formulas by using nested function calls
- Add writing of cell ranges for formulas in BIFF2/BIFF5
- Simplification of code e.g. by replacing the huge case instruction in TsSpreadBiffWriter.FormulaElementKindToExcelTokenID by a look-up table.
Fixes mantis issue #25718; patch by wp; thanks a lot!

6a4ff4c1c2 * Correction to r2863: use ISO 8601 format for WriteDateTime text output (currently every format except BIFF8 xls). 
Ensures resulting files are interoperable regardless of OS locale settings, conforming to date/time cell support in BIFF8.

abd8d0bea8 + Add date/time/datetime read/write support for BIFF8 xls format. No plans for earlier formats though the code could be adapted 
+ XLS BIFF8: added DATE and TIME worksheet functions to RPN formula
* Allow writing formulas,numbers etc using cardinals increasing row/column limits for formats that support it.
* Add checks for text cell size limits when writing xls, xml. If exceeded, cell text will be truncated (better than corrupting the xls file - e.g. try to open it with Excel 2002 - as happens now with xls format)
* Formats that use fpspreadsheet zip have extra checks to prevent crashes for invalid zip dates
+ Use FPC built-in zip format when using FPC 2.7.1+ as it has fixes/improvements (e.g. zip64 support)
+ Added FPCUnit test suite to test reading and reading writing files. For now uses BIFF8 xls; contributions for other formats and more tests welcome. See the tests subdirectory.
+ Add link to msodumper tool for reference/debugging/troubleshooting .xls output

Fixes Mantis bugtracker issue #25388
