User Story

As an app developer, I want to config the default apply composer in MVVM

For example,

<div viewModel="@id('vm') @init('...')">
</div>

is the same as

<div apply="org.zkoss.bind.BindComposer" viewModel="@id('vm') @init('...')">
</div>

"org.zkoss.bind.BindComposer" is the default apply composer in MVVM

Acceptance Criteria

Provide a library property to do the configuration
