Close #10853
Close #10860
Core/Movement:Fix waypointed creature aggro
Core/Spells: Fixed Shadowstep taking the caster out of combat while it shouldn't
Make Cyclone and faerie fire unable to pierce cyclone and banish
Core/Players: Fix haste rating formulas. They're supposed to be the addition, not the multiplication of all available bonuses

- This change matches client formulas
Core/CreatureAI: Implement CreatureAI::TalkToMap for all your map-wide talking needs. Could also replace Battleground::SendChatMessage
Add support for Boost 1.55
Enabling Boost by default as it seems to work under linux aswell (Gentoo 13.0 that is)
Replace ACE signal handling with Boost
Core/Spells: Fix Cheat Death formula
Replace authserver ACE related code with Boost/C++11
Damn you VS default settings..
Restore PCH builds and make GCC happy
Core/RBAC: fix RBAC_PERM_COMMANDS_BE_ASSIGNED_TICKET and RBAC_PERM_LOG_GM_TRADE permissions
Ditched ACE_Singleton in favor of C++11 like Singleton
Replaced ACE_INET_Addr with boost::asio::ip::address
Core/QuestPOI: Mitigate possible DoS with CMSG_QUEST_POI_QUERY

Avoid sending POIs for same quest if the client somehow sent duplicates quest id in same CMSG_QUEST_POI_QUERY packet. This also reduce the effects of possible DoS and increases the difficulty to cause it.
Fix a typo which caused no quest POIs to be sent at all if the client queried data for 25 quests.
Core/Misc: Code cleanup

Remove old unused opcode handler WorldSession::HandlePageQuerySkippedOpcode() for CMSG_PAGE_TEXT_QUERY since it's already handled by WorldSession::HandlePageTextQueryOpcode()
Core/Misc: Added utility method for checking is two sorted containers have a common element
Scripts: Remove unused variables (kept as comment)
