Text/html button

[UziTech]

Add text and html options

html is a boolean attribute to allow the text to be inserted as html

I also made the icon optional to allow for just text buttons

fixes #215
fixes cakecatz/flex-toolbar#111
fixes cakecatz/flex-toolbar#120

  // Adding text button
  toolBar.addButton({
    text: 'hello',
    callback: 'application:about'
  });

  // Text buttons can also have an icon
  toolBar.addButton({
    icon: 'octoface',
    text: 'hello',
    callback: 'application:about'
  });

  // Text buttons can be html
  toolBar.addButton({
    icon: 'octoface',
    text: '<b>BIG</b> button',
    html: true,
    callback: 'application:about'
  });

looks like travis failed because macos build got canceled. @suda can you restart the macos builds?

[UziTech]

@suda any feedback on this?

[UziTech]

@suda I was able to implement this in cakecatz/flex-toolbar#125 but I had to use !important in the css to override the width. So it would be a lot better to implement it in tool-bar so I could remove that style hack.

Oh sorry for keep you waiting! Merging it now :)

Does this close #197?

@edjubuh yes, you can add svg elements with:

toolbar.addbutton({
	tooltip: 'Cherry Pick',
	text: '<svg ...',
	html: true,
	callback: 'git-plus:cherry-pick'
});
