Calculator plugin- Cache/history for query

[jjw24]

Add saving calculator input.

• save calculations as a json file in settings
• will need to figure out how to trigger the save function as calculation query results do not require hitting enter

Discussed in #2615

Since Launchy, I missed this feature not only for calculations, but also for other commands. I tried KP which has a problem with memory limitation/absence. Is there a similar or different problem to add this cache feature to FL?
