* Added basic infrastructure for visibility update in case difference player and current view point.
Just for note: seletect additional arg way beacuse repeatable search object will slow but store pointer will not safe,
so use middle case: get view point pointer early as possible at visibility updates.
* Implement dynamic object and creature activisation while it's target of far sight spell effect
* Use this for SPELL_AURA_BIND_SIGHT, SPELL_AURA_FAR_SIGHT and SPELL_EFFECT_ADD_FARSIGHT.
* Note2: some spyglass like spells let look _around_ at long distance, this hard implement in current grid loading system
Without additional changes and not implemented (you will see empty area without creatures in likes case)
* Also fixed warning spam at CMSG_MOVE_SET_CAN_FLY_ACK receive by use proper packet sructure reading.
Also some code logic cleanups.
Changes let make more cleanups in base map access and other places,
but this chnages not inlcuded in patch.
