HA improvements, high load improvements
- Set higher timeout for the access of the partner management - this allows to reach the partner settings even if the system is under high load
- Improved the performance of the send order sender (via command line, from remote machines)
- Database migration dialog: The database files have been loaded from the client side but needed to be loaded from the server side
- The log refresh for HA did just count the number of transactions but not their state - means sometimes nodes in the cluster did not refresh the transaction log if just a single transaction state changed
- Added synchronization between the file streams and the underlaying file system provider. If multiple nodes access the same files it is required they are physical written to the file system
- Timing problem in the HA overview dialog: Some nodes were shown as offline even if they are already in the cluster
- Update MINA to 2.1.4 (async io framework for client-server architecture)
