Color updates: update text button title color and configure alternative button in LoginEmailViewController (#164)

* Add `UIButton` extension to apply default styles to a plain text button.

* Configure alternative label in `viewWillAppear` in `LoginEmailViewController`.

* Bump pod version.

* Move text button style configuration from `UIButton` extension to `WPStyleGuide+Login`. Update existing usage and configure the "Enter your password instead." text button in `LoginLinkRequestViewController`.
