Made MACScheduler aware of state of ObservationControllers. The major state-
changes are even passed to the SAS database.

Updating OTB database (as a test).

Modification for better support of the PVSS database.

PVSS related enhancements.

State is also set to 'stopped' when program is killed.
customPrep script does not create any datapoints anymore. The DPs are now
part of the install procedure of a PVSS-LOFAR database.

Weekly update after a week of testing the controller chain.

Some minor changes.

Installed signalhandler for PVSS update during quit.

State of the MACScheduler is written to PVSS during destruction. A signal handler is installed
(late enough to override the GCF signal handlers!) that triggers the transition to the
finishing state. In that state, the property is written and a timer is installed because
PVSS database writes are asynchronous. When the timer goes off (1 second) the MACScheduler
is closed.

Bugfix

Made programs compatible with CodeLoggingProcessor.

Added code to update the PVSS Dynamic String Array 'activeObservations'.

Added support for starting the childcontrollers.

Bugfixing after testing.

Moved several sources to their definite place.

First (partially) working chain with MACScheduler and ObservationControl.
Startup sequence is OK.

Renamed state UNKNOWN to state NOSTATE. Changed names of PVSS variables
to their final(?) names.

Merge MAC-CS1-branch with HEAD. See MAC/Journal for changes.

Redesign of Main Control Unit software.
