Bug Description: When I modify files in a project, the project's Modify Date is not updated to reflect this.

Steps To Reproduce:

1. Connect to collaboration server
2. Have project with files created prior to today
3. Open project
4. Open file in project
5. Save file
6. Push file
7. Add file to project
8. Open remote dialog to browse projects
9. Observe modify date on modified project has not been updated to today

Expected Behavior: I expect any changes made in a project to update the project's modify date. This includes snapshot pushes to files in the project, uploads of new files in the project, changes to project metadata, changes to project file metadata, etc.
