Edit value in external editor

[br0xen]

Probably this looks like:

• Saving the value to a temporary file
• executing $EDITOR on that file
• waiting for $EDITOR to be done
• reading the value back in
• deleting temporary file

Please give me this. Please.

This would help a lot, I had to edit a database with some large values (JSON files) and the single line edit dialog didn't really cut it.
There is functionality to export a value, but then there is none to import a value from a file. That would at least provide a workaround.
