Make name optional

[samcragg]

I saw #214 so thought I'd have a go at implementing it, as I do find the name a bit redundant but have left it in for compatibility and in case a different display name is wanted to the code (i.e. where it's not a legal typescript identifier)

I've tried to modify as little as possible by introducing a formatTaskName helper, however, can look at simplifying things further with probably a bigger refactor.
