- removal of the SystemStatusAction launching the individual SingleHostStatusActions,
because the connection was set incorrectly to the last one of the selected
connections and, if an error occurred to that connection, the data collection
for all of them failed.
- proper handling of HTTP.CancelledExceptions.
- replacement of the FlickerFreeListBox by the more versatile DataGridViewEx.
- corrections to reporting progress for individual hosts as well as page totals.
- made collection of client side data more obvious.
