SSS Shader added in 'Swap Shaders', shortucts conflicts addressed.

- New Subsurface Scattering Shader has been added, so Nodes Efficiency Tools 'Swap Shaders' needed to be updated to take SSS into account.
- Revision 55718 changed keyboard shortcuts for 'Find nodes' and 'Make Links with Replace'.
    (Ctrl-F for 'Find Nodes' and Shift-F for 'Make Links with Replace')
    Those changes caused shortcuts conflicts with Nodes Efficiency Tools 'Link Active To Selected'.
    New shortcuts for 'Link Active to Selected are as follows:
        BACK_SLASH - call 'Link Active to Selected' menu
        K - link to all selected, don't replace links.
        Shift-K - link to all selected, replace links.
        QUOTE - link to selected when node name matches, don't replace links.
        Shift - QUOTE - link to selected when node name matches, replace links.
        SEMI_COLON - link to selected when outputs names matche, don't replace links.
        Shift - SEMI_COLON - link to selected when outputs names match, replace links.

'K' key is used as it's the last letter of 'LINK'. QUOTE and SEMI_COLON are used as they are close to BACK_SLASH that call main 'Link Active to Selected' menu.
Any suggestions for using different keys are more than welcome.

1. After importing a structure, the sticks were not selected: fixed
 
2. Small cleanups of the code

3. New feature: The sticks can be represented as entire cylinders. One can 
choose either single cylinders, which are parented to an empty, or one single
mesh object including all sticks. 
This feature is quite suitable for structures, which count more than 1000 
sticks. When the sticks are represented by one single mesh object the
handling in the 3D scene is much faster.
Note that the layout of the preferences in the file dialog had to be also 
changed since there are more options for sticks now.

resolve issues reported by dolf.
(but not all)

1. Don't zoom out when selecting output. Often you want to recheck an area you're working on... and you have to zoom back in again and again.

3. The distorted check is a great tool.. I have the default value at 45 degrees... I think you had it at 15? That's a bit low.

4. The upper limit for thickness check needs to be much higher. If you're working in mm 1 is too low (coloured prints have a lower limit of 2mm)... so make the limit for the check 10 or so.

5. Sharp edge check seems to work for both negative and positive values. There is very much a difference between those when printing... You're usually looking for pointy stuff.

added: Colored Specular Highlights (the only supported uvmaps channels that can work with this feature are alpha and bump, due to POV syntax limitations)
not fixed: vertex colors support broken since BMesh.
