Add ELSE and OR to conditions

[frikky]

The ELSE of a condition (in a branch) could be:

• Jump to a node of choice
• Start a different workflow
• Send an email / SMS / create alert

Don't focus on implementing this until we know the conditions in place make sense.

AND: Add multiple in a row (normal)
OR: Add another branch that is to be checked. If there are multiple branches from the same node, just one of them needs to work.

This will probably never happen, as you can make a node that does this exact thing instead, using the "Opposite" button.
