Proposal: CSS-based blink implementation

[johnnyshields]

The current API allowes user to specify 'blinkBGColor_1' and 'blinkBGColor_2'. I think it may currently be been broken.

I propose to replace these with a new parameter 'tagBlink', which has the following allowed value types:

• string: specifies a class to apply while blinking. defaults to 'tm-tag-blink'
• function: call the function on the affected tag element when blink is triggered
• null/false: do not blink

Unlike the previous implementation, when setting class string can only set one blink color rather than two. If you want two, you'll need to make a custom function.

This will include adding blink styles for each of the semantic color styles, and updating the docs.

Yep, I think it's a much nicer solution.
