Scrolling in console
Feature: Allow to scroll for a specific command in console while leaving it half-entered.
Description: There was a feature in CoD4 and other games that when you're entering a long command in console you can use keyboard arrows to select the needed one in the list of commands. Some commands are too long.
Motivation: This feature should be added to the client, so player can write less text and select console commands faster as it was done in previous games.
