use pointsize from material dialog for polyline spheres

A few adjustments were needed regarding #54 

- switch default draw mode to POINT_SPHERE_SCREEN instead of POINT_SPHERE, because this is the more intuitive mode

- POINT_SPHERE takes the radius from the material dialog

- The material dialog spinboxes for point size and line length are converted to QDoubleSpinbox to allow for floating point values. A world scale radius of 1 in POINT_SPHERE mode is already too big, so values between 0 and 1 are needed here

Introduce and Use Customizeable Side Pane Area

In order to use screen real estate more effectively, replace the stretch space between plugin titles and detach button with a widget that is customizeable by plugins. 

Also added a use case for this new feature to make the Datacontrol plugin interface sleeker.

Feature cmake folders msvc

I added a cmake macro to display the files on msvc grouped by folders.

@moebius  please test this on Visual studio version 2013, i was not able to test it since the installation on Krone crashes when opening the project files. Since i saw this behaviour already a few ays ago when @lyon wanted to compile something on the same machine, i assume there might be something broken or bad configured on Krone. ;)
