There are still some file types that cannot be matched.
Add a standalone Open With service.
Users can configure shortcut for this service in System Preferences.
Without this commit, kitty would fail to compile on macOS 10.12 with the error "use of undeclared identifier".
This problem was introduced in f7be4fab48d2e7cc7bbf9942d8a9fdbfba85b274, where some code was moved to a different file, without moving the corresponding `#define` statements.
Most apps on macOS have the menu items for opening and closing tabs and windows in the "File" menu. Since this doesn't really apply to Terminal emulators, both Terminal.app and iTerm2 have them in the "Shell" menu instead.
This change makes the menu bar of kitty more consistent with these applications.
The spotlight search in the "Help" menu of the menu bar did not appear when the system language is set to a language other than English. macOS magically adds the search box when the text in that menu matches the translation of "Help" in the system language. On my German system for example replacing "Help" with "Hilfe" will make the search box appear again. This is however not a good solution for kitty as it would require implementing localization support for all languages. Removing `CFBundleAllowMixedLocalizations=True` from `setup.py` also brings back the search box but that may break the locale again. The line was added in 8818b5d8df686c0e340ef3d15a069bf54082d112 to fix an issue related to https://github.com/kovidgoyal/kitty/issues/1233.
Luckily I found a seemingly undocumented function that helps us out here, which does not rely the text comparison magic.
The new User Notifications Framework is only available on macOS 10.14 and above, while the old NSUserNotification API is deprecated in macOS 11 (Big Sur) and will probably be removed in the future.
This commit compiles a simple test program to see if the Framework is available and then uses either the new or the old API.
This used to be implemented before 4e3c6e52aad41b9deb98d052c806f4a84846b782, when the now deprecated notifications framework was still being used.
Implement it again for feature parity.
