attempt to word break for textbox

[asturur]

It looks working good.
Please test are welcome.

Someone should get an idea about how to handle text like
" Lorem ipsum dolor "
with trailing spaces or consecutive spaces.

Dang I'm not set up with support for separate classes (eg. textbox.class.js)
Right now, just have everything included in one fabric.js file
Will try and separate things so I can test properly

check how to download and build a branch

@asturur works great!

A few comments:

1. I'd suggest that breakWords be true by default since that is more inline which how I imagine people will use Textbox ... to limit text within a box.
2. In other textbox implementations (e.g. the textarea tag in a browser), when you start typing a long word somewhere in the middle of a line, the textbox wraps the long word onto the next line in an attempt to make it fit all in one line. I think the Textbox class should do the same.
