Roadmap 1.1 [Done]

=====================

• Non-blocking SQL queries
• Use max packet length from MySQL in DBInsert class to know when it is appropriate to execute the query
• Use of more C++11 features:
  • final/override
  • emplace for map insertions
• Remove virtual specifier from all functions that aren't being overridden
• Use integers instead of floating point numbers for item weight and player capacity
