Propagates styles from bottom up

[jtreminio]

Test code:

<?php

use PhpSchool\CliMenu\CliMenu;
use PhpSchool\CliMenu\Builder\CliMenuBuilder;

require_once(__DIR__ . '/../vendor/autoload.php');

$menu = (new CliMenuBuilder)
    ->setBackgroundColour('black')
    ->setForegroundColour('green')
    ->setTitle('Color Test #1')
    ->addLineBreak()
    ->addSubMenu('Submenu #1', function (CliMenuBuilder $b) {
        $b->setTitle('Color Test #2')
            ->addLineBreak()
            ->addSubMenu('Submenu #2', function (CliMenuBuilder $b) {
                $b->setTitle('Color Test #3')
                    ->addLineBreak()
                    ->addItem('Foo #6', function (CliMenu $menu) {})
                    ->addItem('Foo #7', function (CliMenu $menu) {})
                    ->addLineBreak()
                ;
            })
            ->addItem('Foo #4', function (CliMenu $menu) {})
            ->addItem('Foo #5', function (CliMenu $menu) {})
            ->addLineBreak()
        ;
    })
    ->addItem('Foo #2', function (CliMenu $menu) {})
    ->addItem('Foo #3', function (CliMenu $menu) {})

Fixes #201

Waits until CliMenuBuilder() is called to pass styles from the root-level CliMenu and drilling into all children submenus.

If a submenu has custom styles, it passes that to its children, ignoring the parent's style.

[jtreminio]

Added support for propagating to split item children.

<?php

use PhpSchool\CliMenu\Builder\SplitItemBuilder;
use PhpSchool\CliMenu\CliMenu;
use PhpSchool\CliMenu\Builder\CliMenuBuilder;

require_once(__DIR__ . '/../vendor/autoload.php');

$itemCallable = function (CliMenu $menu) {
    echo $menu->getSelectedItem()->getText();
};

$menu = (new CliMenuBuilder)
    ->setTitle('Select a Language')
    ->setUncheckedMarker('o ')
    ->setCheckedMarker('x ')
    ->addSplitItem(function (SplitItemBuilder $b) use ($itemCallable) {
        $b->setGutter(5)
            ->addCheckboxItem('2-A', $itemCallable)
            ->addSubMenu('Options', function (CliMenuBuilder $b) use ($itemCallable) {
                $b->setTitle('CLI Menu > Options')
                    ->addCheckboxItem('Rust', $itemCallable)
                    ->addLineBreak('-');
            })
        ;
    })
    ->build();

$menu->open();
