Issue with exporting minimized panels.

[Neel]

Exporting minimized panels fail to delete panel and throw id error on restore.

http://jspanel.de/documentation/exportPanels.html

1. create jsPanel
2. minimize one of the loaded panels
3. click export and delete (normalized one is destroyed)
4. restore panel (normalized one loads fine, other throws an id error)

Hi there and thanks for reporting.
I made a liitle change that seems to fix it but needs some more testing before I release a fixed version. Just made a quick test in FF, Chrome, Opera, EDGE and IE11.

To test yourself download http://jspanel.de/downloads/jsPanel-2.6.2.zip
