Change type of the all property in the constructor (#73)

This commit corrects the type of the `all` property in the `mitt` constructor function, such that it properly reflects a list of `Handler` functions rather than a single `Handler` function.

This makes it possible to provide an argument to the `all` property in TypeScript projects without casting the argument to the `any` type and with proper error feedback.
