Add input text for active element (iOS)

Implements

Hello!
I implemented a way to type text without needing to pass a locator.

Usage:

Click Text                        E-mail
Input Text                        ${None}                 [email protected]\n
Clear Text                        ${None}

It types text if keyboard is visible, so I need to click a textfield first.

I have tested with iOS, but I don't know if it will work with android.
