Pull request #216 (2019-06-01 03:22:11)

Added missing AskOpts
This PR continues the work in #201  and adds the remaining `AskOpts`:

* `survey.WithHelpInput` to change the rune that prompts look for to provide help.
* `survey.WithIconSet`  to change the icons
* `survey.WithFilter` to change the default filter applied to Select/MultiSelect

This has to go in after #214 since it relies on the `PromptConfig` which was introduced it that PR.

AlecAivazis: @coryb there is now parity across the methods in the Prompt interface. Not sure why I wanted to avoid another file in the root of the project when there are already so many...
AlecAivazis: I thought a bit more about this API and i think one of two things needs to happen. Either I should remove '`WithHelpInput`  or `HelpInput` should be removed from the `IconSet` struct. It's not clear from the API what would happen if you passed both `WithHelpInput` and a `WithIconSet` that modified the icon since they modify the same field in the icon set.
 
Any preference @coryb? Keeping it in the `IconSet` has a smaller API surface since its kind of tucked away. But it's also not really an "icon" like the others since it's input and would never include any kind of color configuration regardless of how #141 shakes out.

-options are backed by more complex types and filtering might need to occur on more metadata than just the displayed name.
