Font-size change with CTRL +/-/mouse wheel in Serial monitor and Console/messages pane

[jaggzh]

Dynamic font-size adjustment currently functions in the editing area.
CTRL +/- and CTRL Mousewheel work beautifully for this purpose (and are obviously the standard shortcuts for it).

HOWEVER, if someone could implement this in at least two other areas it would be extremely useful to many people:

1. The Console Window (the place where you see compile/upload messages), and
2. The Serial Monitor

I am aware of features being settable, so before anyone informs me of this, I am specifically referring to the ability to do it dynamically, as is allowed in the Editor. :)

Perhaps needless to say: This is especially useful for the visually-impaired, who have to constantly balance how much material they can see (as much text as they can) with the size needed to see it (which changes with the time of day, position, rubbing their eyes, etc.)

(Too different of an issue, but perhaps while looking into this, it'd be on someone's mind: arduino/arduino-ide#1495)
