SheetJS af3df44633 version bump 0.11.5: "string" type
- proper JS string input / output type
- bower main now uses full version (fixes #820 h/t @newmesiss)
- DOM parse directly acts on innerHTML (see #779 h/t @danxfisher)
- unicode core props and ext props (fixes #822 h/t @fureweb-com)
- shim update for IE10/11
- test refresh and flow checks
