Increase length of ip address fields for IPv6 support

[Guite]

If the web server is configured as dual stack allowing both IPv4 and IPv6 requests it may happen that the ip address gathered from $_SERVER['REMOTE_ADDR'] is a IPv6 address. This can lead to problems if corresponding database fields are too short. Ip address fields should therefore be enlarged to at least 39 chars.

SecurityCenter is fine (has 40 chars already):
https://github.com/zikula/core/blob/1.4/src/system/SecurityCenterModule/Entity/IntrusionEntity.php#L84

PageLock needs a change:
https://github.com/zikula/core/blob/1.4/src/system/PageLockModule/Entity/PageLockEntity.php#L84

Users needs a change for sessions:
https://github.com/zikula/core/blob/1.4/src/system/UsersModule/Entity/UserSessionEntity.php#L40

I don't know if there are other additional fields in the core, this needs to be checked, too.
