Syntax for conditional check for errors in README doesn't work

[fatuhoku]

There's a few instances in the README where errors are handled with this conditional:

  } else if task.error() {

However I cannot get this to compile.

error is not a function, but rather a property - try removing parenthesis at the end of the if task.error().
We do need to update the docs, I agree. Will keep this open for now then, PRs are very welcome.

Fixed with #230, thanks @wzs!
