Fix python-heal-selection.py missing on CentOS7

• 1 After copying files from resynthesizer.tar_0.gz into ~/.gimp-2-8/plug-ins directory, the Gimp 2.8 says it can not find python-heal-selection.py when using Gimp->Filters->Enhance->Heal Selection...
  
• 2 The solution is to build the resynthesizer project https://github.com/bootchk/resynthesizer from source according to build instructions and then add new path to the Gimp->Edit->Preferences->Folders->Plug-ins:
  /usr/local/lib/gimp/2.0/plug-ins
  
• 3 I have also removed the files previously copyied to the ~/.gimp-2-8/plugins from the original resynthesizer.tar_0.gz archive, but be carefull with this.
  
• 4 cd GITHUB/resynthesizer-master
  ./autogen.sh
  make
  sudo make install
  
• N Missing libs during ./autogen.sh (prerequisities):
  yum install glibc*
  yum install gimp-devel-tools
