Previews for matparams (#334)

* Immediate updates
AssetManager static hack to load textures in preview...

* Previews for all matparams(?)
Updatable floats and colors

* Previews for all matparams(?)
Updatable floats and colors
(SDK Core project)

* Rich editors for colors, texture and float nodes. Simple editors for vecs and bools.

* Revert "Merge branch 'master' into previews_for_matparams"

This reverts commit 2d4920e95620534b64e5ab8a0f3cd2329851c93c, reversing
changes made to bed7dea707538130b5a97d3e16dcb0dd601303e8.

* Merge branch 'master' into HEAD

# Conflicts:
#	jme3-core/src/com/jme3/gde/core/editor/nodes/NodePanel.java

* fixing disastreous merge commit

* one more file

* mending

* mending

* sorting for shadernodeblock. inclusive?

* live updates for backpanel

* clean up

* fixes #339 Attribute nodes are expected to be named "Attr"

* fixes #335 properly. better sorting and sorting on new mapping

* Revert "Immediate updates AssetManager static hack to load textures in preview..."

This reverts commit d08c87f08455ef4699576af6d15097003805c8b2.
