allow access to global command history when using a specifc history

[ailin-nemui]

also add history loading method

[ailin-nemui]

usage: ctrl+up/down

this can come in handy if you use /window history named or /set window_history on, but want to recall something from one of the other windows' histories

sample script for your autorun:

use strict;
use warnings;
use YAML::Tiny;

my $histfile = Irssi::get_irssi_dir()."/history";

my ($hist) = eval { YAML::Tiny::LoadFile($histfile) };
if ($hist) {
    Irssi::UI::Window::load_history_entries(undef, @$hist);
}

Irssi::signal_add 'gui exit' => sub {
    if (Irssi::settings_get_bool('settings_autosave')) {
	YAML::Tiny::DumpFile($histfile, [ Irssi::UI::Window::get_history_entries(undef) ] )
    }
}

Huh. Why?

[ailin-nemui]

fixed

Good stuff.

The commit log / PR title could use some more love. I mean, global window history is the default behavior, but being able to use global history while window history is enabled is a very good feature.

Not sure I fully understand what g_history is supposed to hold.

Leaving the job of persisting history to a perl script is a weird choice (not wrong, but not one i'd choose) but I guess you like perl, and more APIs don't hurt. It's a good example of adding more perl stuff, I guess.

I renamed g_history to history_entries
