0.95 -> 0.01 to prevent eye-poppingly white specular highlights.

As opposed to (mostly) camera space. Oops.
While somewhat hidden with point lights, the problem became apparent with
directional lights.
Now that we have proper directional lights, change the default light, that is
used when no light components are specified at all, from point to directional
since this is cheaper and provides less surprises with arbitrary scenes.
Also remove the duplicate phongalpha vertex shader in the process.

Two animated lights with the position of the lights represented
as spheres.

QAbstractLight becomes QLight and gets its own backend node. This way we can
easily gather all lights for the scene and filter them when building render
commands.
Both the frontend and backend remain a subclass of (Q)ShaderData
but will not be part of the ordinary ShaderData component list. This
prevents mixing up ShaderDatas and Lights but allows reusing the same
underlying infrastructure so that properties can automatically be
transformed for example. It is worth noting that the position property for
lights is now removed: the position is determined by the entity's (to which
the light component belongs) position.
A number of changes are made to ShaderData itself as backend subclassing
with different managers is not straightforward.
For now the distance between the rendered entity and the entity with
the light component is calculated and lights will be chosen based on
this distance. A framegraph node for controlling this will be added
in future patches.
No uniform setting or shader changes are included here.
