Images from formatters inside cmd

[jcubic]

Expected behavior

Images should be rendered inside cmd

Actual behavior

Bracket is rendered after the image

Steps to reproduce

$.terminal.defaults.formatters = [[/:\)/g, '[[@;;;;https://unpkg.com/emoji-datasource-twitter@4.1.0/img/twitter/64/1f603.png]]']]
term.insert(':)');

I doubt anyone would like to render images in cmd but this should work since formatter can return any formatting including images.

Also cmd don't render attributes for some reason:

$.terminal.defaults.formatters = [[/:\)/g, '[[@;;;;https://unpkg.com/emoji-datasource-twitter@4.1.0/img/twitter/64/1f603.png;{"style":"width:32px"}]]']]
term.settings().allowedAttributes.push('style')
term.insert(':)');

with echo it works fine.

Bracket fixed by #550 but one issue is that you can't put cursor after the command. it always at last character.
