 * does not support image series

Depending on StringProperty's display type, its property widget shows either just the QLineEdit, or additionally a browse button that pops up a QFileDialog for either loading or saving a file, or choosing a directory.

closes #43

Refactoring AbstractProcessor::process() for clearer semantics and better and more uniform handling of invalidation levels:
 * AbstractProcessor::process() now calls updateShader(), updateProperties() and/or updateResult() with respect to the current invalidation level
 * each processor shall no longer override process() but the updateXYZ() methods, at minimum updateResult()
 * AbstractProcessor::process() takes care of (un)locking the processor itself (no need to do this from the outside anymore)

Further implicit changes:
 * Removed redundant HasPropertyCollection::updateProperties()

Loading can be done with genericImageReader, however, assertion fails for sliders. thread ownership issues

* Moving to Apache 2.0 license
* Updated AUTHORS.txt

Fixes -Wignored-qualifiers

Floating point properties were previously typedef'd to specific
instantiations of NumericProperty. Now that we have
FloatingPointProperty, which extends NumericProperty to control how many
decimal places should be shown when displaying the property's value, all
typedefs for floating point properties have been updated to point to it
instead.

As a result, many processors and pipelines needed to have their includes
and/or constructors fixed to import and work with the new typedefs.

=== ATTENTION: CAMPVis does compile, but image representation conversion not yet functional again! ===

Revising ImageData concept step 2:
 * Removed all ImageDataXYZ classes
 * Introducing GenericAbstractImageRepresentation<T> and its GenericAbstractImageRepresentation<T>::ScopedRepresentation
 * Updated all processors and pipelines to use ImageRepresentationXYZ instead of ImageDataXYZ and the implicit conversion feature

The modules package is now itsself modular. Every subdirectory in modules/ builds its own submodule that can be individually switched on and off. Therefore each submodule needs its own submodule.cmake file to specify the build targets etc.
This is neat!

Major revisions to the class layout / data structure:
 * Introduced ImageDataConverter interface (still not really happy with the design)
 * Removed support for Int64 and double images from WeaklyTypedPointer
 * Added ImageDataGL::bind()
 * AbstractProcessor::init() method, gets called by AbstractPipeline::init()
 * added VisualizationProcessor

Updated/New processors:
 * fixed MhdImageReader
 * SliceExtractor stub for very simple slice rendering

Various fixes:
 * DataContaier: managing of DataHandle ownership
 * GenericImageDataLocal::getSubImage()
 * ImageDataRenderTarget bindings
 * GenericProperty
 * linking issues with StringUtils

Hence, all this enables the first usable implementation of a specific pipeline:
The SliceVis pipeline combines MhdImageReader and SliceExtractor for a very simple 2D slice rendering
