Feature Request: Functionality to manipulate the typingDelay time globally

[schmitzl]

I want to manipulate the time for the typingDelay for my SocketBot. However, I would have to set the typingDelay for every message individually. This is far too much work for something, that could as well be solved with a configuration variable. I do not want to change the original formula to calculate the typingDelay as it works nicely and takes the message length into account. What I want instead is an additional factor in that calculation, that I can set for bot. This typingDelayFactor should be 1 by default and with this use the original calculation for the typingDelay. However, as a user, I can also increase the typing speed of the bot by setting it to something lower than 1 or I can turn my bot into a really slow typer by setting it to e.g. 5. This gives a lot of flexibility while still taking the message length into account.
I will implement the changes for a typingDelayFactor and create a pull request.
