FormBinder OSGi support

Hi Matti, how are you?
Im using Formbinder sucefully on a OSGi enviroment, and um thinking if its not a good idea to make the formbinder jar a OSGi ready bundle, as Vaadin itself is.

As this addon is very small, it will be simply to continue provinding OSGi support on it. For now, just addin this entry's on the Manifest.mf will be enought:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: org.vaadin.addon.formbinder
Bundle-SymbolicName: org.vaadin.addon.formbinder
Bundle-Version: 2.1.2
Bundle-Vendor: Matti Tahvonen
Export-Package: org.vaadin.addon.formbinder;uses:="com.vaadin.data,com.v
 aadin.ui";version="2.1.2"
Import-Package: com.vaadin.data;version="[6.0.0,7.0.0)",com.vaadin.ui;ve
 rsion="[6.0.0,7.0.0)"

Thanks!!!!
