#452 GraphViz Plugin Strips "style" keyword

[JoshG]

The GraphViz plugin seems to remove the "style" keyword from the DOT text entered, but only on a "save". It is retained for "preview". For example:

{graphviz}
digraph
{
test [style=filled, fillcolor=blue];

}
{graphviz}

works as expected on preview, but after a save it is converted to:

{graphviz}
digraph
{
test [ fillcolor=blue];

}
{graphviz}
