Need to know the version of the FM that is running

[jsturdy]

Brief summary of issue

Currently, it's not possible to easily see the version of the jar file that is being used as the FM, which makes debugging difficult in the case that people upload different versions.

Types of issue

• Feature request (request for change which adds functionality)

Possible Solution

• Probably the simplest would be to add the git hash to the webpage, as I think HCAL have done in some way
