Add basic support for spawning entities through Lua

 - Not very well tested, but is able to spawn info_ff_scripts like flags and have them work like normal
 - Added baseentity:SetName(string name)
 - Added global function SpawnEntity(string entity_class_name, string entity_name) that returns the entity spawned or nil if unsuccessful (example: `local entity = SpawnEntity("info_ff_script", "red_flag")`)
 - Added global function SpawnEntity(string entity_class_name) that returns the entity spawned or nil if unsuccessful (example: `local entity = SpawnEntity("info_ff_script")`)
 - Closes #63
