TUSCANY-2837 - Updates to Implementation Widget

[Luciano Resende <lu...@gmail.com>]

I have committed the following changes related to TUSCANY-2837 :
   - Added extension points to Implementation Widget  (core-web)
   - Updated ATOM (binding-atom-js) and JSON-RPC (binding-atom-js)
bindings using these extensions to provide Javascript Proxies
   - Updated sample apps with new required dependencies

Note that with these changes, applications that use Widget will need
to add new dependencies in order to the client js be generated
properly :

        <dependency>
            <groupId>org.apache.tuscany.sca</groupId>
            <artifactId>tuscany-binding-atom-js</artifactId>
            <version>1.5-SNAPSHOT</version>
            <scope>runtime</scope>
        </dependency>

        <dependency>
            <groupId>org.apache.tuscany.sca</groupId>
            <artifactId>tuscany-binding-jsonrpc-js</artifactId>
            <version>1.5-SNAPSHOT</version>
            <scope>runtime</scope>
        </dependency>

Please let me know if you have comments or if you find any issues in this area.
