Make it easier to see if there are any uncommitted changes in version control

[yaustar]

It would be great to have visible indication here if there are uncommitted changes

At the moment, the process to find out if there are changes is to do a diff which can be expensive on larger projects.

Users can save a lot more time if all the information is present already.

I spoke to @zachpeterpaul and we could implement a 'quick diff' that would only check if there are any changes rather than list the changes itself.

However, this can still be slow as it has to download a copy of the previous checkpoint to diff against on the backend.

There's also 'last edited' timestamp in the database somewhere that is used for project list sorting that could be used?

This requires some investigation.
