qp edit feature request

[addman2]

For sake of easier editing in aiida environment, it would be helpfull if there were special flags for only creating temporary editing file and reading temporary editing file:

qp edit -w </path/to/the/file.txt> Will store the current state
qp edit -r </path/to/the file.txt> Will read the state from a file
