Here is my little approvement to this mod.

New mod showing friends currently online: (see here: https://oc.tc/forums/topics/516c308dba60878cbf000305)

I also removed ModLoader use: Forge is an advanced ModLoader, better use only Forge methods

Only compatible with forge. Added compatibility with forge for minecraft 1.5.1 (were some problem like buttonList which became private).

If you try, by starting a full new forge environment you aren't able to compile this correctly.
I corrected them to make my mod work with this.

PS: Sorry just realized there are a lot of code changes for nothing, this is because of NetBeans auto formatting :3
