Add more default modes

Previously only 3 default modes are loaded: form, tree, code

Now, there are form, tree, code, preview, text

To pass an array of more than 3 items to @json blade directive, a variable has to be used to get around a bug in the @json directive that does not allow the direct passing of an array of more than 3 items.

jsoneditor library bumped to 9.9.0. Tested this bumped version in production for months before tagging this release.
