0.7.0-beta.5

API changes:

• Applications shouldn't call register.parse() anymore, nor CustomElement#attachedCallback(). It happens automatically. Therefore, you don't need to require() "delite/register" unless you are declaring your own widgets. There is a new register.deliver() method that you can call if you need for widgets to be parsed synchronously.
• Removed deprecated Widget#startup() method.
• refreshRendering() may get called before widget is attached to the document. Actually, that was true before too, but now it's more likely.
• The Widget#isLeftToRight() method was replaced by an effectiveDir property, indicating the widget's dir setting, or the setting it inherits. When effectivDir's value changes, it triggers a notification to computeProperties() and refreshRendering(), just like when other property values change.

Bug fixes:

• KeyNav: navigate on click, not pointerdown. Avoids problem on tablets/phones where scrolling navigates to a node. Fixes #379.
• Widget#getParent() returns null if this.parentNode is null. #405
• HasDropDown does better job cleaning up old popups (by detaching them from the document)

Enhancements:

• Call parser and attachedCallback() / detachedCallback() automatically. Also, attachedCallback() will only be executed once, even if it's called multiple times. Happens asynchronously, but there's a register.deliver() method to make it happen synchronously.
• HasDropDown: add focusOnPointerOpen and focusOnKeyboardOpen properties.
• Add has("inherited-dir") flag to inherit direction from any ancestor
• Allow observing changes to any native property
• Call deliver() automatically when widgets created. Fixes #385.
• Made deliver() work synchronously on native properties too. Previously on Chrome the native property updates were always delivered asynchronously.
• Allow CustomElements to be attached and then detached repeatedly.
