fixed wrong code indentation
improved export of coupled patches to OPENFOAM
fixed export directory bug
fixed crash for wrongly formatted files
equidistant failsafe to avoid strange node distributions
avoid conflicts with 1.4.x and newer versions
better export and updated links
improved detection of deteriorated point distributions
fixed smoothing bug and improved height computation

Layer height smoothing on feature edges did not work due to odd-even
decoupling. The current system is based on boundary codes and needs to be
change din order to work with the new surface algorithm (starting from
enGrid 1.5).

The ratio between bottom and top area of a prism can now be limited.
The angle between these two faces can also be limited.
(m_FaceSizeLowerLimit, m_FaceSizeUpperLimit, m_FaceAngleLimit)
airfoil import for newer Blender versions
increased precision for double settings
Deb packaging: Added ability to build on Ubuntu 13.04.
