* remove Detours package, move code to /source/detours/
* remove Detours code from /source/vcl-styles-utils/delphi-detours-library/, so we have only one version
* remove Vcl.FormsFix.pas, as the bugs I fixed with that are most likely fixed with the move to Delphi 10. See https://www.heidisql.com/forum.php?t=19141 for the original bug report.
* only vcl-styles-utils uses the Detours lib from now on
