Follows-up42c97fa(I82ed4ade),63c5943a9(Ic71346196). This commit makes no functional changes, but it reduces overhead from the SyntaxHighlight code when interacting with other features, such as elaborate modals or other hashchange-heavy code paths that a gadget might produce. It uses vanilla DOM instead of jQuery where possible, and adds an early return rather than fairly deep continuation no-ops. Change-Id: I2264f6f398193802f05c738bad4c294da007fb27
