Define $element.data('bs.tokenfield') earlier.

Define $element.data('bs.tokenfield') at the beginning of Tokenfield() instead of after initialization so the Tokenfield object is also available through $(this).data('bs.tokenfield') in events triggered during initialization. This is useful when tokenfield:createtoken or tokenfield:createdtoken events have been attached before initialization, so they are run on page load if the tokenfield input has a default value on page load.

Before this fix you would get an error if you tried to use $(this).data('bs.tokenfield').$input inside a tokenfield:createtoken event that was bound before tokenfield initialization like this

$('#tokenfield')
    .on('tokenfield:createtoken', function(){
        var $input = $(this).data('bs.tokenfield').$input;
        // Do something with $input
    })
    .tokenfield()

You could just bind the event after .tokenfield() but then the create event would not be run on initialization (on page load) when tokens are created from the default value attribute of the #tokenfield input.

Before this fix you could use a workaround of recreating the tokens after initialization to fire the create events like so $('#tokenfield').tokenfield('setTokens', $('#tokenfield').tokenfield('getTokens')); but this is not needed anymore after this commit.

This fixes issue #151

Someone might want to write a test case to ensure that this doesn't break later. I don't yet have experience on writing tests in a JS environment.

I was also wondering should I run grunt build and include the compiled files in dist/ when submitting a pull request like this? Or do you prefer to build separately?
