Huge output support (> 100k lines)

[bugy]

At the moment Script server is capable of handling of 10-100k lines of output (depending on the machine and amount of text formatting in the output). This is mostly limited by browser capabilities of displaying lots of html elements.

To make Script server to work with even larger outputs, it should not render full output at once, but instead do lazy loading on scrolling (i.e. elements are created only when user scrolls to them). May be this library could be used: https://clusterize.js.org/

The drawback of this approach would be copying output to clipboard and may be some lags on scrolling. So this feature should be configurable per script and should be disabled by default.
