Active `TabBar` is not highlighted initially

[pombadev]

Hello, I'm following the example verbatim.

https://github.com/deinstapel/cursive-tabs/blob/52e94cb6bc686a209127ce7bf9b7087a2d602ba2/examples/fullscreen.rs#L1-L60

The active tab name is not highlighted initially even though active tab is being set.

https://github.com/deinstapel/cursive-tabs/blob/52e94cb6bc686a209127ce7bf9b7087a2d602ba2/examples/fullscreen.rs#L34

Image to illustrate potential bug and expected behavior.

Could be the same issue as #4

I'm pretty new to rust, but i think this is to do with how the buttons are added to the TabBar of the TabPanel. The TabBar isn't public so i can't see how to set the active button easily, but i have a work around below.

Problem: Adding a tab using the "add_tab/with_tab" methods always sets the active TabBar Button to the last button. https://github.com/deinstapel/cursive-tabs/blob/52e94cb6bc686a209127ce7bf9b7087a2d602ba2/src/bar.rs#L121-L138

Adding a tab using the "add_tab_at" method with an index (pos) sets the active TabBarButton to that index. https://github.com/deinstapel/cursive-tabs/blob/52e94cb6bc686a209127ce7bf9b7087a2d602ba2/src/bar.rs#L189-L205 Workaround: Add the desired active tab after you've added the other tabs. This will set it's TabBar Button to be active. Of course you'll need the "add_tab_at" method so the panel will need to be mutable.

    let mut panel = TabPanel::new().with_tab(TextView::new(TAB_1).with_name("1"))
        .with_tab(TextView::new(TAB_2).with_name("2"))
        .with_tab(TextView::new(TAB_3).with_name("3"))
        .with_tab(PaddedView::lrtb(2, 2, 1, 1, TextArea::new()).with_name("4"))
        .with_bar_alignment(Align::End);
    panel.add_tab_at(TextView::new(TAB_0).with_name("0"), 0);
    panel.set_active_tab("0").unwrap_or_else(|_| {
        panic!("Could not set the first tab as active tab! This is probably an issue with the implementation in the lib. Please report!");
    });

How to focus on a tab panel's internal component, instead of one of the tabs?

For example, I have a text editor, I hope to focus on it, instead of the containing tab panel.

Thanks
