Provide OSGi Metadata

[GoogleCodeExporter]

As many libraries already do, it would be great if ez-vcard would provide OSGi 
metadata out-of-the-box, too, so that it can be easily used in an OSGi 
environment.

Changes to the POM:
 1. Replace:
<packaging>jar</packaging>
with
<packaging>bundle</packaging>

 2. Add:
<build>
        <plugins>
            ...
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <version>2.4.0</version>
                <extensions>true</extensions>
            </plugin>
            ...
        </plugins>
    </build>

 3. Eyeball the generated Manifest file and tweak it if needed by configuring the maven-bundle-plugin

What is the expected output?
A Manifest with OSGi metadata

What is the actual output?
A Manifest without OSGi metadata

What version of ez-vcard are you using?
0.9.0

What version of Java are you using?
1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08
