add to bower about jquery-tbltree

[gagiks]

I'm not familiar with what is bower repo, could you please provide more info?

Callback CREATE() function does not exist in your code.
In your documentation you have twice the EXPAND function. One have to change it COLLAPSE.

For callback create please look to the example on page:
http://gagiks.github.io/jquery-tbltree/examples/events.html

Regarding the second comment I didn't find issue in provided doc.

Thanks,
Gagik.
