Additional logging, with new conf.json settings to enable/disable logging of specific events:

"logFactionCreate": true,  - log faction creation
"logFactionDisband": true,  - log factions being disbanded, by command or by circumstance
"logFactionJoin": true,  - log player joining a faction
"logFactionKick": true,  - log player being kicked from a faction
"logFactionLeave": true,  - log player leaving a faction
"logLandClaims": true,  - log land being claimed (including safe zone and war zone)
"logLandUnclaims": true,  - log land being unclaimed (including safe zone and war zone)
"logMoneyTransactions": true,  - log money being deposited, withdrawn, and otherwise transferred in relation to faction banks

Also a fix for a potential NPE from players logging out and Spout appearance handler referencing them afterwards
