b8c1cf2961 fpspreadsheet: Add support for reading background colors in biff8 and fpspreadsheetgrid.
Add automatic test case for colors (fails since some colors are not yet written correctly, fails also for blank cells which are not yet read).

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!

Still to do: add test cases for invalid format strings

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
