[feature] padding between components

[TheElegantCoding]

i will like to dont repeat the margin between all the components i the layout of alpha so if a have

        layout = {
            header,
            { type = 'padding', val = 1 },
            header_welcome,
            { type = 'padding', val = 1 },
            title('Quick links', 16),
            { type = 'padding', val = 1 },
            shortcuts,
            { type = 'padding', val = 1 },
            title('Project', 11),
            { type = 'padding', val = 1 },
            projects,
            { type = 'padding', val = 1 },
            fortune,
            { type = 'padding', val = 1 },
            github,
        },

i always repeat the padding, even if i make a function is the same so my idea is to have a global option in opts that allow to have padding between elements like this

    layout = {
        header,
        header_welcome,
        title('Quick links', 16),
        shortcuts,
        title('Project', 11),
        projects,
        fortune,
        github,
    },
    opts = {
        padding = 1
    }

it is like margin property but this is in elements
