Description of problem: 
fedora specific spyder.desktop file doesn't has a mime-type conncetion for x-python files. So in GNOME it's not possible to open python files with spyder via a double click as spyder doesn't show up in the list  of available applications.


Version-Release number of selected component (if applicable):
24 (as far as I know, others version probably as well)


How reproducible:
install python3-spyder via normal package management, open file manager, try to open python file 


Steps to Reproduce:
1. install spyder
2. open nautilus
3. create python file with .py ending
4. double click on python file


Actual results:
dialog with available programs for python files opens but spyder is not listed


Expected results:
dialog with available programs for python files opens and spyder shows up


Additional info:
As fedora specific spyder.desktop file
