hyperHTML.adopt(liveNode)

[WebReflection]

After the introduction of viperHTML.adoptable = true, capable of creating a compact and compression friendly way to delimit all interpolations of a template literals, hyperHTML would like to re-introduce this ability lost wtih v2 release because unstable.

All the basics are working but there are still two cases I cannot code cover because failing:

• nodes with just textContent behaves differently, when text action is used the adoption shuold work properly
• when there are levels outside those already explored, findNode(...) internal function does not handle well the level variable together with the index

Once these two outstanding bugs are fixed, I will think about releasing v3 to include adopt within the library and branch out v2 for eventual emergency fixes.

Coverage remained the same at ?% when pulling 4f1d747 on re-adopt into c689e81 on master.
