0.11.0

Breaking changes

• Cursive::{ncurses, pancurses, termion} now return
  io::Result<Self> instead of panicking. Cursive::default() still unwraps.
  • Also added Cursive::try_new for failible backends.
• Replaced set_fps(i32) with set_autorefresh(bool)
• Finder::find_id() is renamed to call_on_id(), and a proper
  find_id() was added instead.
• Updated the Backend trait for a simpler input system
• Updated to Rust 2018 edition (now requires rustc > 1.31)
• Cursive::clear() now takes &mut self

API updates

• Add a logging implementation (logger::init()) and a DebugConsole
  (cursive::toggle_debug_console())
• Add user-data to Cursive.
  • Cursive::set_user_data() can store some user-defined data structure.
  • Cursive::user_data() and Cursive::with_user_data() can be used to
    access the data.
• Add StackView::remove_layer()
• Add CircularFocus view (and bring proper circular focus to dialogs)
• Add HideableView::is_visible()
• Add type CbSink = Sender<Box<CbFunc>> as an alias for the return type of
  Cursive::cb_sink()
• Add LinearLayout::{insert_child, swap_children, set_weight} for more
  in-place modifications.
• Add Printer::{cropped_centered,shrinked_centered}

Improvements

• Updated termion backend to use direct /dev/tty access for improved performance.
• Enabled raw mode for ncurses and pancurses. Among other improvements, this
  lets applications receive Ctrl+S and Ctrl+Q events.

Bugfixes

• Fixed overflow check for titles in Dialog and Panel
