- 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)

Remove parameter AData in several methods of the readers/writers and replace it by FWorkbook passed at creation.
Add unit tests for font and color support. No issues.

Fix painting error of cell borders in fpspreadsheetgrid.
Add/complete reading/writing support for horizontal alignment, cell background and cell borders to BIFF2.

- 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!

Ensures resulting files are interoperable regardless of OS locale settings, conforming to date/time cell support in BIFF8.

+ 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

xlsbiff5 and xlsbiff8 must be descendants of a general biff class as many unsupported tags are common for both formats, some of them even common with biff2.
Added a list of unsupported tags to xlsbiff5 (IFDEFed) to easilly catch tags that must be supported like RK and MULRK which prevent it for load completly many xls files. xlsbiff8 must support them also.

Now BIFF 5 & 8 should be possible to be generated in non Windows environment but this fact has not been tested.
To use the older mode replace uses "fpolebasic" by "fpolestorage".
Extensive tests are needed.
