Added ons-keyboard-active and ons-keyboard-inactive directives. Also added code to trigger events when software keyboard is shown and hidden.
typo
Try to bind the keyboard events a few times before giving up, the plugins take some time to load.
Fixed style.
Bind events on 'deviceready'.
Remove event handlers after the component has been destroyed to prevent memory leaks.
Display error message when Keyboard plugin isn't loaded. Don't check for cordova, since we're listening for deviceready anyway.
