[Bug] Console lag / freeze when there are a lot of prints

[3ti65]

The problem is the amount of binding updates for each console line. it basically triggers a redraw of the text view. we should probably buffer these and then batch update.

How to Repro:

Start up an RM Server and try to do other things within VU-Launcher while it prints a lot. You can't close the server or open a Client while it's printing a lot.
