[mr3081] rework lock chain and references counter in TerrainInfo v0.2. requires previous changes in TerrainMgr.
- make SmartPtr's locked (as in original code)
[mr3082] Hardcode some achievement id (don't complete "First on server" achieves for GMs)
[mr3083] Improve "First on server" achievements. Use flags instead of hardcoded ids.

thx to Dramacydal for idea.
