User informed when new version available

[hayleycd]

Would it be possible for the user to be notified that a newer version is available when they run the scanner?

I ran 1.1 this morning before upgrading to 1.2. I knew 1.2 had just been released, but I was thinking it would have been nice to see a line outputted (potentially in color to stand out) that informed me of the available upgrade.

Hmm, this is indeed nice but I'm not sure how this would fit into user workflows, given that there are multiple distribution channels.

i.e. if I'm a Linux user pulling this in via my package manager, and there's a new upstream version available via GitHub, it may not be available in the package manager.

This piqued my interest as something to explore contributing.

My thought was if the binary could introspect itself to conditionalise the behaviour to only running when it is confident it's been compiled locally from source, as opposed to packaged by a Linux distribution, this would be of greatest benefit to its user...
