JB Workaround CardDAV-Sync

Jul 22, 2015

The workaround now disables itself for a couple of seconds after booting the device. That ensures the original sync app can take over the account. That should fix all the issues with the stock editor.

- new in 1.4
Change disable/enable sequence
Allow workaround to be called from CardDAV-Sync. I hope that fixes all issues with removed accounts.
On shutdown the app ensures the workaround is enabled on the next start (hence the new permission)
