Adding a contextual menu option to files to remove metadata from a document

[Félix Brezo]

As posted in https://bugs.launchpad.net/pantheon-mail/+bug/1559665 for pantheon-mail and so as to prevent data leakage via metada, I feel that it may be useful to add an opton to the contextual menus that appear in pantheon-files to "Remove metadata from file" to manually clean them from photos, office docs and .pdf amongst others.

The tool that could be called in the background is the commandline exiftool:

sudo apt-get install exif
exiftool -all= example.pdf

This could be linked with bug 1196148 - If the properties window were to have a tab showing metadata then it could include an option to delete it. This would avoid lengthening the context menu.
