Cleanup dead code

[memelotsqui]

There is alot of dead code lying around (intialTraits, blinker.js, download model from component), lets make a pr for each dead code block and make sure everything is working correctly after removing the code.

initial traits are not called from app.jsx, but directly from the option-utils script: *app.jsx

option-utils import option-utils function

We are no longer using blinker.js, only blinkManager as it considers loading multiple models

ExportMenu.jsx is no longer using download call from internal code, but from downloadUtils
