/**
|
||||
* jQuery Favicon Notify
|
||||
*
|
||||
* Updates the favicon to notify the user of changes. In the original tests I
|
||||
* had an embedded font collection to allow any charachers - I decided that the
|
||||
* ~130Kb and added complexity was overkill. As such it now uses a manual glyph
|
||||
* set meaning that only numerical notifications are possible.
