HTML5: game never finishes loading if full screen is enabled in options

[SirAthos]

Version: Stencyl build 9300 from 2017-02-14

How to repro: enable "Settings -> Web -> Start in full screen"

What happens: the game never gets out of the "loading" progress bar

Why: Engine.IMG_BASE is initialized to empty string and never gets set to anything else, so all references to "assets/graphics/" + Engine.IMG_BASE + "/anything/else" fail to load due to wrong URL. This is visible in browser console errors.
When full screen is not enabled in settings, it gets set in line 382 of Universal.hx:          Engine.IMG_BASE = MyAssets.gameImageBase;

(This works fine on other platforms)

Fullscreen issues should be fixed in 3.5.
