Fix for an annoying UWE bug

I'm tired of seeing it being reported through my error report system.
Only add shared/server plugins to baseconfig

It was adding the chatbox plugin.
Fixed large space issue in the chatbox

As old messages were removed, if they were more than 1 line in height
they would leave that as a gap at the bottom as the panel would not
resize itself down.

Also fixed mouse wheel scrolling getting faster as the panel size grows.
Enable the chatbox by default

I think all the major bugs are gone now.
Startup messages can be used in Initialise

They're now displayed after the server sends us the list of shared
plugins to load.
A clearer and better time to string method

This one is readable...
Workaround UWE bug

Sometimes players are replaced and set up for a new team, but then not
added to the team list and thus the game just leaves them as their old
player as an assertion fails.
