[Feature Request] - Allow users to be able to zoom into the screen using mouse / keyboard

[roboirc]

There is a menu option from which you can zoom the channel window above the nick list. But its only available via menu. Would be nice to be able to do this via mouse wheel up / down and / or keyboard key. Thanks!

By screen I mean the main IRC chat window so that fonts change size according to wheel up / down.
