NEW : File type association with camitk-imp.exe on Windows for opening.
Each launch of an instance of IMP register it for file opening. Standard volume image and mesh files type (in the share/testdata directory) are handled. See the ImpMainWindow constructor for registered file type. Note : file association only works on Windows. git-svn-id: svn+ssh://scm.forge.imag.fr/var/lib/gforge/chroot/scmrepos/svn/camitk/trunk/camitk@513 ec899d31-69d1-42ba-9299-647d76f65fb3
