fix bug 1084011

remove links to broken community websites
The .c9/project.settings is auto-generated and auto-updated. It was customized in #2325 in an effort to make things easier, sorry it added a little confusion. @sgarrity's suggestion in IRC to add a .gitignore to prevent this from happening was a good one. @heavensmile would you mind doing something similar to the following?
```
cd .c9
git checkout HEAD~2 project.settings
git add project.settings
cp ../media/img/openstandard/.gitignore .
git add .gitignore
git ci -m 'Ignore changes to .c9'
```
