Template Editor font size adjustment

[ic360-com]

Being a little bit old school, I generally like to edit Templates using the built-in Editor, rather than export to files.
I'm finding the font size for the Template code a little bit too large.

Would it be possible to add a Setting to the Template Settings for controlling the font size?

I realise I can use the browser font sizing, but obviously this changes all the font sizes (including the menus) when it's just the Template code size I'd like to control.

We are going to add codemirror_fontsize system configuration override for this. I think setting it to value like 0.9rem would make font size more in line with the rest of text in CP
