We were using action log level for a lot of
things because by default MT does not seem
to capture info logs to stderr. On "production"
servers though this makes too much noise and
makes it hard to find actual player actions.
Servers that want info logging will just have
to configure/compile it in.
Use high-res version in a few places we were using integer-res
timer before. This should e.g. smooth time variation of wind
strength for ambient sounds.
