Complete and improve lookup blocks

[Flashing-Blinkenlights]

Feature branch: 5.1

The sets of blocks in lookup is fairly messy, with some blocks missing and a lot of repetition. Steps should be taken to clean up this information and tests made to make sure no blocks are overlooked.

• Use set comprehensions for block variations
• Eliminate redundancy where possibly
• Highlight redundancies
• If possible, cross-reference with client's assets

[Flashing-Blinkenlights]

Updated block lists, tidied up groups, adjusted and added tests to check for missing/incorrect blocks
