added scintilla 5.2.4 and lexilla 5.1.8

[chcg]

Release 5.2.4
Released 10 July 2022.
Fix hiding selection when selection layer is SC_LAYER_UNDER_TEXT. Bug #2334.
Fix bad background colour for additional, secondary, and inactive selections when printing. Bug #2335.
Fix failures on GTK with non-UTF-8 text when multi-threading due to character set conversion code that was not thread-safe.
Fix crash when printing on Win32 in bidirectional mode with a non-empty selection.

Release 5.1.8

Released 10 July 2022.
F#: Recognize nested comments in F#. [Issue #93](https://github.com/ScintillaOrg/lexilla/issues/93).
MS SQL: Recognize nested comments in Transact-SQL. [Issue #87](https://github.com/ScintillaOrg/lexilla/issues/87).
MS SQL: Preference data types more consistently to not depend on how lexing is broken up into segments. This is needed because there are keywords that are both data type names and function names such as 'CHAR'. [Issue #90](https://github.com/ScintillaOrg/lexilla/issues/90).
PowerShell: Fix single quoted strings to not treat backtick as escape. [Pull request #92](https://github.com/ScintillaOrg/lexilla/pull/92).
Visual Prolog: Treat \r\n line ends the same as \n. This makes testing easier. Add test case. [Issue #83](https://github.com/ScintillaOrg/lexilla/issues/83).
Visual Prolog: Allow disabling verbatim strings. [Pull request #89](https://github.com/ScintillaOrg/lexilla/pull/89).
Visual Prolog: Support backquoted strings. [Pull request #89](https://github.com/ScintillaOrg/lexilla/pull/89).

Fix bad background colour for additional, secondary, and inactive selections when printing. Bug #2335.

Just a heads up — this will not fix that issue in N++'s case. It required some post-release work that's only in Scintilla's trunk at the moment: #11826 (comment)

Can confirm the PowerShell parser fix in lexilla 5.1.8 mentioned in this Notepad++ commit works!

Lexilla 5.1.9 was released, Scintilla 5.3.0 probably will appear August 27 2022.

@ArkadiuszMichalski
Thank you for the info. Just checked on Scintilla official site, 5.3.0 is released.
For the sake of stability, let's keep scintilla 5.2.4 and lexilla 5.1.8 for Notepad++ v8.4.5 release.

@rdipardo
Thank you for the heads up. I saw Bug #2335 has been fixed in Scintilla 5.3.0.
So it will be fixed in the future versions (or I can do a hot fix by using the patch in Notepad++ next release).
