ability to not process keys

[ghost]

deny processing of inputs by boolean result, basically:

use liner::{Event, Context};
use termion::event::Key;

fn main() {
    let mut line = Context::new();

    line.read_line("$ ", &mut |Event {editor, kind}| -> bool {
        match kind {
            EventKind::BeforeKey(Key::Char(c)) => !c.is_whitespace(),
            _ => true
        }
    });
}

output:

./target/release/liner-test
$ 
# <SPACE> <SPACE> <SPACE> <SPACE>
$ 
# <SPACE> <SPACE> <SPACE> a <SPACE> b <SPACE> c <SPACE>
$ abc

i accomplished this currently, and terribly with Editor::undo.
