Began according/toggle/slider view for lop #4857

This is the generic approach.  It makes any node slidable.  We'll later make a whitelist of supported content types.

(The other approach is to make a view mode for each content type.  These view modes will automagically appear in the LOP.  I can't start that till I have a list of content types though.)

All the changes are contained in the slider.inc plugin, except for a hook_preprocess_node.
Forgot to add new file. #4586

I wonder if `git commit -a` can have this behavior changed.

Restarted sv list slider as view mode #4856

This time it's a view mode.  hook_field_display_node_alter ensures it looks just like slider.  os_preprocess_node adds javascript, classes.  Now to tweak display for each content type.
Fix cv for slide teaser.  Last update in same container.  #4856
Omitted faq from slide_teaser.  Redundant with its teaser #4856
Removed slide_teaser from presentations #4856

Teaser was already compressed down to one line.  NO point in clicking a line to hide other words on the line.
Fix accordion LOP for software #4856
List of publications slider fix #4856

Biblio was only loading a teaser's markup when viewmode was teaser, regardless of field settings.
Fixed bio LOP slider #4856

This use case was stupid but it was a trivial fix.  Teaser mode was hiding the title so there was nothing to toggle off of.
Removed image from LOP accordion profile mode #3846

Without the floating image, this mode works just great.
Added css cursor change to make LOP toggle more obvious #4856
kill grey background and border around os slide when inside the lop slider. #4856
