Multiple dataset support & renamed events

This is a pretty major release that involves some breaking changes.

Some events have been renamed (again). Sorry about that, but I just wasn't happy with them.
I believe the new event names make much more sense and are semantically correct.

• tokenfield:preparetoken is now tokenfield:createtoken
• tokenfield:createtoken is now tokenfield:createdtoken

There are 2 new events:

• tokenfield:editedtoken - fires when a token is ready for editing
• tokenfield:removedtoken - fires after a token is removed from DOM

Other changes and improvements in this release:

• Fixed css path in bower.json #100
• Edit mode fixed when only one token present
• Support readonly inputs
• minLength is now tested against label, instead of value
• Always pass full datum object to typeahead events #116
• Multiple datasets for Typeahead are now supported
• Built-in event handlers can now be cancelled on some events by calling event.preventDefault() or doing return false

Maintenance release

• Tokenfield now respects tabindex
• Tweak invalid token border color
• Fixes for tokenfield input width calculation

Fix build #2

Sorry again! This time, I forgot to bump the package version. I must not have had a very good sleep.

Fix build. Update & improve styles. Make better use of LESS.

Sorry - I forgot to build the last 2 releases, which means they do not include the updated code in dist folder. Please upgrade to this one ASAP.

Changes:

• Fixed disabled token hover styling
• Make better use of LESS

JSDOM tests

• Refactored tests to jsdom. Tests can now be run with npm rum
