* build: enable /Zc:lambda for MSVC
MSVC keeps its legacy lambda processor under /std:c++17, which rejects
reading a constexpr constant inside a lambda that does not capture it
(C3493). No other compiler requires that capture, and clang reports it as
an unused one, so the two cannot both be satisfied without the flag.
/Zc:lambda selects the conforming lambda parser that clang and GCC
already use. It is implied by /std:c++20 and /permissive-, so it is only
needed while we are on C++17. clang-cl is conforming already and does not
take the flag.
It requires VS2019 16.8, so build_release_vs.bat now says 16.8+.
* build: clear 237 unused lambda capture warnings
236 captures across 81 files, 142 of them `this`. Removing an unused
capture changes no behavior; clang does not report a capture whose type
has a non-trivial destructor, so nothing held only to extend an object's
lifetime is in this set.
Nine of them are the second half of the warning, "is not required to be
captured for this use", where the capture is a const or constexpr value
the body does read. Those depend on the /Zc:lambda change in the previous
commit. One of them, in FillRectilinear.cpp, had been worked around with
an #ifndef __APPLE__ guard around the capture list, which is now gone.
GUI_ObjectTableSettings.cpp captured its reset button only to read it
inside #ifdef __WXOSX_MAC__. That branch now takes the button from the
event it is already handling.
* build: fail configure on MSVC older than 19.28 instead of dropping /Zc:lambda
cl.exe answers an unrecognized /Zc: sub-option with warning D9002 and keeps
going, so on VS2019 before 16.8 the flag is silently ignored and the build
instead dies with C3493 in FillRectilinear.cpp, nowhere near the cause.
* fix: delete three locals that are now unused
Their only remaining use was the lambda capture this branch removed. The
Clang builds set -Wno-unused-variable, so the build never flagged them.

* Fix calls to depreciated wxPen constructor
* Fix use of wxTimerEvent
* Fix unrecognized character escape sequence
* Fix signed/unsigned mismatch
At least as much as possible without significantly altering parts of the application
* Clean unreferenced variables
* fix mistyped namespace selector
* Update deprecated calls
* Fix preprocessor statement
* Remove empty switch statements
* Change int vector used as bool to bool vector
* Remove empty control statements and related unused code
* Change multi character constant to string constant
* Fix discarded return value
json::parse was being called on the object, rather than statically like it should be. Also, the value was not being captured.
* Rename ICON_SIZE def used by MultiMachine
By having the definition in the header, it causes issues when other files define ICON_SIZE. By renaming it to MM_ICON_SIZE, this lessens the issue. It would probably be ideal to have the definitions in the respective .cpp that use them, but it would make it less convenient to update the values if needed in the future.
* Remove unused includes
* Fix linux/macOS compilation
* Hide unused-function errors on non-Windows systems
