Additional options for tags

[mrbubblesort]

I added these options for tags:
bgBox - (true|false) background box on/off
bgBoxPadX - (int) x padding on tag
bgBoxPadY - (int) y padding on tag
bgBoxStroke - (string) outline color for bg box
bgBoxColor - (string) color for bg box
bgBoxRadius - (int) radius of bg box corners

For example, this would make the tags look like a bootstrap labels or buttons (http://getbootstrap.com/components/#labels):
$('#tag-canvas').tagcanvas({
'textColour' : '#FFFFFF',
'bgBox': true,
'bgBoxPadX' : 6,
'bgBoxPadY' : 10,
'bgBoxStroke' : "#5BC0DE",
'bgBoxColor' : "#5BC0DE",
'bgBoxRadius' : 5,
});

+1 to make it easier to use with Bootstrap. Nice to see this library in GitHub.

I've had a quick look over this, and found a couple of minor problems:

1. The padding and radius options don't take into account the "txtScale" value - this is easy to fix in the Tproto.Measure function by multiplying (like s * this.height and s * t.shadowBlur).
2. With the "outlineMethod" set to "colour", the whole tag is opaque in the outline colour, so you can't read it. Not sure if there is an easy fix for this.
3. Not really a problem, but "bgBoxColor" for the option name when I've spelled the other options "textColour" and "outlineColour" could cause confusion.

Otherwise, it looks good.

OK, no problem. I'll try to get that in this week then. Thanks for the input.
