Update zm_create.sql

Todays computer hardware and internet speeds allow for a much more responsive user interface to be ran. I suggest to optimize these values in the "High bandwidth" profile for today's technology. These values were established at least 8 years ago... There's no risk for the user because on a fresh install and new logins, new browsers "Low bandwidth" is always the default. Optimizing these values produce no noticeable load increase on modern hardware, and a snapy, pleasant user interface if desired.

Also increased event image digits because I often run into situations where very long events run out of file naming digits (max 999 files is too short, that's only 40 seconds).
