Update Licensing

[ColonelPanics]

This PR updates the licensing details in the library scripts.

Licensing was updated with the following sed (on mac, won't work quite the same on Linux):

sed -i '' -e 's/201.* Stephen.*Ltd./2019-present Alces Flight Ltd./g;s/Alces Inventoryware/Inventoryware/g;s/alces-software/openflighthpc/g' FILE

This looks like it's still licensed under AGPL rather than EPL?

I'd also go for calling it "Flight Inventory" rather than "Inventoryware" which is more consistent with where we're taking thes tools.

@mjtko I'll sort out the naming now. The headers are still referring to the old license, you're right, license.txt is using EPL but the libs aren't... seding...

[DavidMarchant]

This all looks fine by me - merge whenever you're done

[mjtko]

Looks like the README.md needs some updates still, and there are some instances of the inventoryware repo name referred to rather than the spanking new flight-inventory naming.

[ColonelPanics]

ta, double checking

[mjtko]

README's still got wrong license and copyright, but other than that LGTM!

[ColonelPanics]

@mjtko thanks for your 🏓 on this!

Rebased on develop to add templates_config.rb so I could add the new licensing
