What's new in this version:

* Inno Setup Preprocessor (ISPP) changes:
- ISPP is now an official part of Inno Setup and is included in the standard Inno Setup installer instead of only being included in the QuickStart Pack installer.
- It is now possible to enable ISPP preprocessing on .isl files by adding a line saying #preproc ispp at the top of the .isl file.
- With the exception of Exec, ReadIni, and WriteIni, all ISPP functions that take filenames have been changed to interpret the filenames as relative to SourcePath instead of the current directory. Additionally, these functions, the #include directive, and the #file directive now support prefix expansion (e.g. \'compiler:\') in filenames.
- The #include directive no longer searches the current directory.
- Builtins.iss has been renamed to ISPPBuiltins.iss.
- The Compiler IDE no longer displays a separate ISPP version number in its title bar.
* Compiler IDE changes:
- The Edit | Replace | Replace All command now actually replaces all occurrences, instead of doing a Delphi-style \"From Cursor\" replacement. Also it now counts all replacements as a single undo action and shows how many occurrences were replaced.
- Unicode change: Added a new File | Save Encoding submenu. It now defaults to preserving the UTF-8 BOM of existing files, even if the UTF-8 encoding isn\'t really needed.
* Unicode change: Added support for Unicode characters in DLL filenames (not specified directly in the script, but returned by constants like {app}). This fixes the \"Cannot Import\" error seen with for example the CodeDll.iss example script when uninstalling from an {app} path containing non-ANSI characters.
* Two new Setup exit codes related to the Preparing to Install stage were added. See the help file for more information.
* Minor tweaks.
