Superficial cleanup to replace all instances of "gAgentAvatar" with "gAgentAvatarp".

Superficial cleanup to replace all instances of "LLVOAvatarSelf *avatarp = gAgent.getAvatarObject" with "gAgentAvatar".

Superficial cleanup so that all instances of gAgent.getAvatarObject() use "LLVOAvatarSelf *avatarp = gAgent.getAvatarObject".

Minor superficial cleanup to have all references to getAvatarObject use LLVOAvatarSelf *avatarp = gAgent.getAvatarObject()

Fixed normal bug EXT-5207 - Region Maturity level not displayed on nav bar when coordinates are enabled and parcel got no name.
