Add font option to CKEditor.
I found two plugins for this but it is ok to use other if it is more suitable:
First one is better to use by my opinion just make sure font sizes dont mess up when this plugin is added, because plugin icnludes font size option as well and we already have it in "%". So we are not changing font sizes, they should keep current values 50%-450%.
"Fonts" option should be placed before "Font size" option.
For font list I suggest these fonts to choose from:
Arial - default font
Open Sans: https://fonts.google.com/specimen/Open+Sans
Open Sans Condensed: https://fonts.google.com/specimen/Open+Sans+Condensed
Dancing Script: https://fonts.google.com/specimen/Dancing+Script
User can choose font in CP when editing texts
