History: PluginButton

!! Nicer navigation-style buttons

Let's enhance ((doc:PluginButton)) to be able to do this:
{img type="src" src="https://i.stack.imgur.com/7HzwE.jpg"}
{img type="src" src="https://www.prepbootstrap.com/Content/images/template/metrotiles.png"}
{img type="src" src="https://edwiser.org/wp-content/uploads/2016/06/adaptable-two-e1466678134269-981x1024.png"}

To add:
* location of image
** left (default)
** above
** below
** right
* Size: 1 to 10 (affects both text and icon)
* image: this is to be an alternative to icon (because sometimes we don't have the right icon)
* mouseover (to add additional info while still keep layout nice)

* Question: Is the text under the icon ("PHP", etc.) meant to be part of the button? To me it looks like a caption for the button. If it is meant to be part of the button, then there could be a plugin parameter to switch between text display-inline and text display-block (unless both a button text and "caption" are wanted - then there'd need to be a new parameter for that) which I suppose would be implemented with the "text position" parameter. Also there need to be separate text size controls for icon and text. {sign user="chibaguy" datetime="2017-11-02T03:24:42+00:00"}
** Yes, it's meant to be part of it and could be in the box. I added other examples. {sign user="marclaporte" datetime="2017-11-08T10:59:40+00:00"}
