HA improvements, high load improvements
<ul>
<li>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</li>
<li>Improved the performance of the send order sender (via command line, from remote machines)</li>
<li>Database migration dialog: The database files have been loaded from the client side but needed to be loaded from the server side</li>
<li>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</li>
<li>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</li>
<li>Timing problem in the HA overview dialog: Some nodes were shown as offline even if they are already in the cluster</li>
<li>Update MINA to 2.1.4 (async io framework for client-server architecture)</li>
</ul>
