[Feature request] Adding line delay and character delay when pasting content

[tfuzeau]

Hello,

When working with some devices like switches or firewall, if you copy too many thinks without delay, the device isn't able to handle the flow rate and miss some configuration.

Having a way to add delay with pasting stuff is really helpful for such operation. Those delays already exist in the Script section, it would be wonderful to get the same on the Pasting part. Other software like SecureSRT have this ability.

Thank you very much for your work!
