Fixed Papi support since Clip changed the method to register new placeholders (damn you clip

).
Also added alot of new placeholders as suggested by you. These are:
- Total Clans , %epicset-clans_total_clans% gives the number of clans registered currently.
- Balance, %epicset-clans_balance% gives balance formatted with commas (123,456 )
- Balance Formatted, %epicset-clans_balance_formatted% Gives balance with a prefix (100k etc)
- Balance raw, %epicset-clans_balance_raw% Gives balance as is (used by other plugins)
- Player kills, %epicset-clans_kills% Gives clan kills of a player
- Player Deaths, %epicset-clans_deaths% Gives clan deaths of a player
- Allies, %epicset-clans_allies% Gives all allies of the clan
- Truces, %epicset-clans_truces% Gives Truces of a clan.
- Top clans:
Added all of the placeholders for top clans using the following pattern:
%epicset-clans_top_[position]_[placeholder]%
where position is a
two digit number for the position of the clan &
placeholder is any previous placeholder. For example
%epicset-clans_top_01_leader%
will give us the leader name of the first clan.
Also fixed duplicate clans bug.
