Checkin release notes
Fix typo
Remove unnecessary typecasts
Do not export ng::paragraph_t and supporting to_s function
Move handling of invisible character mapping to ng::context_t
Fix deprecation warnings
Keep settings items in bundle item chooser sorted by scope rank

Previously when we entered a filter string the sorting would be based on how good a match the filter string was.
Add overstrike style to eclipsed settings in bundle item chooser
Update dialog-1.x plug-in
Do not assume CC/CXX is a single executable

The downside is that we no longer have our .o files depend on the compiler (so we need to do a clean build after upgrading the compiler) and if there is a space in the path to the compiler, it will fail.

The upside is that we can let CC/CXX be a command with arguments, e.g. ‘xcrun clang’.
Do not specify SDK version as using ‘latest’ is generally desired

If we need to build with a specific version we can include it in CC/CXX using the --sdk argument.
Call developer shell tools via xcrun instead of using $xcodedir
Don’t perform checks to see if user’s compiler is good enough

The codebase no longer require a cutting edge compiler so we simply use clang via xcrun.
