- remove "void ExceptionHandlingDecorator::setDataValidity(DataValidity newValidity)"
- add "void ExceptionHandlingDecorator::setOwner(EntityOwner* owner)" and remove owner setting in constructor

FixMe:
These tests have to be revised; they do not test the framework
interfaces but implementation details. They miss checking if
the invalidation reflects on control system variables.

- New flag parameter for ExceptionHandlingDecorator::genericTransfer.
  Method does not invalidate data if flag invalidateOnFailure is set to
  false.
- Write related methods in ExceptionHandlingDecorator set
  invalidateOnFailure flag to false

Changes resolve ticket #57.

Adjust CMakeList to use add_dependency instead of FIND_PACKAGE for DeviceAccess library - now all path to headers are correctly added to the project when ControlSystemAdapter lib and DeviceAccess lib are installed in different directories.

- ConfigReader is in ApplicationCore.h, but was including ApplicationCore.h itself
- Added include guards to ApplicationCore.h, although it's not stricktly needed (all included headers have one). Might speed up complilation because it makes it easier for the parser.

Device support for history

device_support_for_history

add two more ignores related to eclipse projects.

This is needed to add all device variables to e.g. the history module.

Connecting a device only works if the PVs are readonly! So one has to
use the logical name mapping backend. This also allows to select only a
subset of the device PV to be added to the history module.

If the hdf5 library is not available, the MicroDAQ module is automatically not build. You don't have to specify -DBUILD_MICRODAQ=OFF to make cmake run through.

I observed that, after reading the message sometimes the log level was
wrong. Most likely because it was updated after the message was read.
Now the log level is bound to the message. This also reduces the number
ctk variables.

Fix missing object name in the example.

It allows you to check how the controller behaves and to monitor the changes in doocs histories, for instance.
