* Fixed path processing bug of the Matlab scripting box preventing Matlab launch on Linux
 * Changed the Matlab boxes and scenarios to ask for the Matlab executable instead of the setting being platform-specific (although on Windows, giving just the path works too, hence this change should be compatible with older Matlab-box using scenarios).
 * Fixed some compilation warnings
 * Deprecated the Matlab filter box. Please use the scripting box instead.
modules/fs:
 + Added a function to get the parent path of a path
cmake-modules:
 * Fixed the alternative way to detect Matlab on Linux and added support for upper-case MATLAB folder (2013a default install does this, for example)
