Affects Version/s: None
Fix Version/s: None
Implement the Import Export user interface using the /export/ and /import/ action.
The /export/ action should ask a few questions:
x List spaces to export (default to all)
x Include Versions (default to yes)
The export should call the package plugin in "backup" mode and export as a zip.
You can see some example code in velocity calling the package plugin here
