Add cursor support for prompts

[klammbueddel]

Hi,

Great library for building CLI applications, thank you! One question regarding prompts. Is it possible to add support to move the cursor to any position in the input? For example, when I press the left cursor, a ^[[D is added. Support for Pos1 and End would be great too.

Thank you

Christian
