Integration with GNU screen; based on tmux.kak - Hack: kak sets `/proc/self/fd/0 -> /dev/null`. Get the client process tty because Screen needs to know the controlling terminal. Else Screen will use the last known tty and will open new windows on a different terminal if one is connected.

provide-module screen %{
Implement smarter detection of windowing environments. This patch centralises the loading of windowing environments, in order to ensure that by default only a single module is loaded, rather than the current code which can load multiple potentially incompatible modules; and in order to provide the user with more control over the loading of windowing modules. The patch introduces a new str-list option `windowing_modules` which defines an ordered list of windowing modules to attempt to load. Modules are loaded in the order specified in the list until a module loads without error, at which point the process finishes. When loaded each windowing module tests the environment to determine whether it should load (e.g. the tmux module tests to see if it's being run within a tmux session), and if it determines that it should then it completes its loading without error. If it doesn't detect an appropriate environment then it returns an error, and the module loading logic tries the next module. The user can override the default `windowing_modules` list to specify their preferred modules (i.e. they can put kitty ahead of tmux if that's their preference, or they can leave out the x11 modules alltogether). In addition, if the `windowing_modules` option is an empty list this bypasses the environment detection logic completely, and allows the modules to be loaded manually - this allows a user to replace the windowing module loading logic with their own manual set up.

Do not reparse %sh{...} strings Automatic reparsing of %sh{...}, while convenient in many cases, can be surprising as well, and can lead to security problems: 'echo %sh{ printf "foo\necho bar" }' runs 'echo foo', then 'echo bar'. we make this danger explicit, and we fix the 'nop %sh{...}' pattern. To reparse %sh{...} strings, they can be passed to evaluate-commands, which has been fixed to work in every cases where %sh{...} reparsing was used..
