P4D is now ready for Delphi 13 Florence

[pyscripter 833]

As per title.  The MultiInstaller in the Install subdirectory has also been updated and now installs P4D in both the 32-bit and 64-bit IDEs.   It is the fastest way to install P4D.  Just clone the repo and run MultiInstaller.  It only takes a few seconds to install in both IDEs and configure the search paths.  The provided setup.ini expects the folder to be called P4D.  If not, you need to edit the setup.ini file accordingly. The only catch is that in the dialog box you should specify the parent folder of "P4D" (i.e. the folder containing the directory to which you have copied/cloned P4D) and not the P4D folder itself.
