Add support for adding icons to the CommandList.

[rouilj]

This adds support for placing icons to the left of the commands.

5 cases are supported:

1. if icon is not defined, it inserts an empty svg that holds 24px of space on the left of the label

2. if icon is null, the space is not held and the label smooshes to the left

3. if icon is a character (in span class="icon"), the character is used. If the string is longer than 24 px, it's cut off.

4. the icon can be an image, css sized to 24x24px.

5. the icon can be an svg, css sized to 24x24px fill set to currentColor.

in each case the icon is a string "<img ...>" "<svg ...>..." etc see:

Don't merge this. I am having a wierd issue where the output html is being shifted.

e.g. rather than

<p><svg><svg><span "command"><span><span "kyb"></span></p>

I see:

<p><span "command"><span><span "kyb"></span><svg><svg></p>

I have no idea what happens here. Sometimes the html is messed up on initial display, sometimes after a search and sometime continuing to search corrects the layout.

I'll reopen it if I can figure out what's happening here.
