Update ChangeLog
1.6.3 final
ownCloudTheme: Fix casing in appName()

Without this fix, the section in the config file uses the wrong name,
leading to re-configuration of the client needed.
Account: Fix cert save/restore from settings. #2160
FolderMan: Fix startFromScratch logic. #1989
raiseDialog: Actually send the XEvent

Amendment to 25c274a0bddd37dd62a9391a9a9f0972a57b70c
csync_vio_local on windows: fix overflow when computing the size of file > 4GiB

MAXDWORD is 0xFFFFFFFF, so if we add one, it overflows and is 0.
We need to cast it to 64 bits before
Propagator: Use csync to get the modification time.

See owncloud/core#9781
