* use EaseIn for the icon button show

Browse Source 
* show the button(s) in .2s rather than the very slow feeling .5s
* don't leak the timeline
* don't connect to the timeline signal more than once
* comment in code that is ifdef'd out anyways
* don't set the svg element for fg and bg unless it exists
* remove some dead code
