Gm ticket handling fixes (#90)

* Fix .ticket response & .ticket close handling

- Now the GMTicket::SetResponseText method will save the response to the right ticket and will nor update all ticket responses for the same character
- Fix potential issue in GMTicketMgr::Create : limiting to the the most recent ticket of the player and avoid potential multiple returns if there is inconsistent data in table
- Fix GMTicket::SetText
- Prevent to update ticket_text for old tickets of the same char when submiting ticket or updating ticket text in game
- Fix item_text GUID generation
- Setting system response when ticket closed without mail response
- Create a PSendSysMessageMultiline function , will split a mangos string in multiple lines if "@@" string is found.

* Fix revision.h after structure change

Need apply Rel21_16_053_GM_tickets_handling_fixes.sql in order to work correctly
