Enable Retina support in Eclipse

To enable retina support locate the Eclipse.app. Then right click and select "Show package contents". Open Contents/Info.plist in a text editor. In the bottom just above

</dict>
</plist>

add the following

<key>NSHighResolutionCapable</key>
<true/>

Then make a copy of the Eclipse.app. Delete the original Eclipse.app and rename the copy to  Eclipse.app. This will force the Info.plist to be recreated in case OS X has cached it.
