1.Don't split a plugin in two versions just for the color, make a cvar so people ca decide if they want to use colors or not(1.8.2 version). Also add the needed includes in your post(chatcolor/colorchat).
2.Since you have an 1.8.2 versions w/o colors, for me it make sense to have that for 1.8.3 too. So, just a cvar and decide how to print.
3.PcvarLoopFrequency should have the lower value as 1.0, not 0.1, it's not needed to check often than that.
4.Everything that is inside if( bomb_receiver ) check should also be inside if ( backpack > 0 && backpack != player )) check. Why ? Becase if you get somehow an invalid entity your code failed and you should not print anything, nor retrieve names.
