Allow developers to use syntax like the following in collection/model bindings:

<Alloy>
    <Model src="someModel"/>
    <Window title="{someModel.title} {someModel.subtitle}"/>
</Alloy>

Basically, instead of assuming the whole property needs to be wrapped in \{\}, allow developers to put as many of them in the attribute as they want.

Feon Sua Xin Miao 2014-07-15 PR: https://github.com/appcelerator/alloy/pull/479 Test app: https://github.com/feons/alloy/tree/ALOY-443/test/apps/testing/ALOY-443 Functional Test: 1. Run the test app on iOS 2. There are multiple data binding notation in the tag attribute, data should be displayed without {}. These 3 test cases failed, which is expected because there are some changes in the generated code. {noformat} advanced/proxy_property_requires [android] matches known good generated code for alloy/widgets/com.foo.widget/controllers/row_bind.js advanced/proxy_property_requires [ios] matches known good generated code for alloy/widgets/com.foo.widget/controllers/row_bind.js advanced/proxy_property_requires [mobileweb] matches known good generated code for alloy/widgets/com.foo.widget/controllers/row_bind.js {noformat}
Tim Poulsen 2014-07-15 Was your intention that this PR support the notation formats shown in ALOY-599? Such as: <Label>{book.title}</Label> <Label>Written by {book.author}</Label> (It does not) Would you also open a separate ticket to update the _generated code for the advanced/proxy_property_requires test app?
Feon Sua Xin Miao 2014-07-16 I'll open a separate ticket to update _generated code. Thanks Tim!
