modified trueskill to show rank number aswell as an ELO rating instead
of the uncertainty.

The ELO is determined by (rank)/50 * 3000;
The maxmimum trueskill rank acheivable is 50
I linearly mapped it to a ELO number of 3000;

This is to make it more similar to how people usually
understand rank

modified plugin to display rank as elo instead of uncertainty
this is more intuitive to the user and what they are used to
modifying to have one decimal place
