implement mctop placeholder

[derpykid300]

%mcmmo_mctop_1%
%mcmmo_mctop_1_[skills]%

pls implement mctop placeholder, which return player name and total skills level

[derpykid300]

and %mcmmo_mctop_1_Overall% for overall ranking

[derpykid300]

As well as %mcmmo_rank_Overall%

[perlsol]

Good idea :)
