#13a Verify EDD version 3.0+

[davejesch]

To test:

• Install EDD < 3.0 on the Target site.
• Attempt to Push EDD Download item from Source. This will display an error in the WPSS metabox on the Source: "The version of Easy Digital Downloads on the Target needs to be at least."
• If the version of EDD cannot be detected on the Target site, a message of "The version of Easy Digital Downloads on the Target site cannot be detected.".
• If the WPSS for EDD add-on is not active on the Target site, a message of "Push failed. WPSiteSync for EDD is not active on Target." is displayed.
