FIX: "Ace Editor cursor wrong misplaced when UI zoom is other than 100%"

- Ace Editor cursor misplaced when UI zoom is other than 100%

The solution is to disable zoom on the editor itself, instead to change the font size if needed.

The fix will be available in next release.

EDIT: changes in CSS instead of settingsController

Closes #106
