Update Scaloid.html

Micro fix in the link to Tweaks in the "Composable components" section.
It's a micro "help" but I check the alternatives scala-based Android projects and yours is really interesting ! Especially because of your documentation (that's why I found strange you've got an "error" :stuck_out_tongue: ) and your talk(s I've just seen the new ones :smile: ).

I truly hope you continue and if I can help I'll do it !
