Polymer documentation blast

[Eric Bidelman]

bcc: polymer-announce

Lots of of new greatness was added to the docs last week. 

API reference

• element.alwaysPrepare - how a <polymer-element> prepares itself
• element.preventDispose
• Binding to attributes with side effects (use underbar attributes: _src, _href, ...)
• Indexed named scoped (e.g. <template repeat="{{ user, i in users }}">):
• Node.unbind() - unbinding a model
• observe blocks -  custom property observers & watching for changes to nested objects
• details on property reflection to attributes

Styling reference

New Styling API reference (has previously undocumented features)

• FOUC prevention
• @polyfill-* directives - how to polyfill complex styling features

A "Guide to Styling elements" article was also updated to include all the new Shadow DOM styling features:

• part/::part()
• ::content
• :host/:host() and theming elements

Please file bugs!
