Dialogs that expect return-delimited list could be forced into showing bigger box

[DanShockley]

There are a bunch of dialogs in FmClipTools where the user will be pasting a return-delimited list, and the default single-line text entry box is disconcerting/confusing. You can't technically specify how big that text entry box should be, but you can force it to be bigger by putting a bunch of carriage returns as the default answer. So, in any usage where the script knows to trim off leading/trailing blank lines, we could force the box to be bigger and make things less confusing for users. It's a bit of a hack, but seems really worth it.

Thanks to Jonathan Nicoletti for the suggestion.
