Component name as variable

Browse source 
I have removed the exception raising when a variable without quotes is given, and keep the variable name until the render function where I'm resolving it if it's a String (which means it's a variable, not a component) then I'm moving the slot parts which relies on the component from __init__ to render after getting the component.
