Added an update version of breeze.d.ts and its associated test 

Hi Boris, 
    I think that it's great that you are keeping this up.

    I am something of a git newbie, so bear with me. 

    I am the author of breeze.js  The changes in this branch are for breeze v 0.84.4. The breeze.d.ts is also available on the breeze website as part of the breeze zip packages.

   Please let me know if this is ( or is not) the correct procedure for making changes.  You can contact me directly at jayt@ideablade.com.
