[FEATURE] Add check for a new version

[eranbrown]

Is your feature request related to a problem? Please describe.
Notify the user if the tool has a new version on GitHub, to prevent users from using old versions without knowing it.
To allow troubleshooting, the upgrade should not be automatic, I think.

Describe the solution you'd like
On launch of JobAnalyzer.py we should check for a newer version.
Not sure if we need to also apply to the parsing scripts ?
