[Implemented] Wider InputRequester

[PB]

I'd like to see the InputRequester have an option Width flag, like so:

Text$ = InputRequester(Title$, Message$, DefaultText$ [,Width])

This would be in pixels. Currently, it's too small for displaying a long prompt,
and for entering a long line of data. And while we're at it, perhaps it could
also support Chr(13)+Chr(10) for multiline prompts?

I have one more request, please - a CANCEL button.
