Core/Group: Fix online state when member logs out
Core/MMAPs: Update recast

Update recast from https://github.com/memononen/recastnavigation/commit/1be9de72d87dcfdecf6bea30f5461745f7d7afe6 to https://github.com/memononen/recastnavigation/commit/740a7ba51600a3c87ce5667ae276a38284a1ce75 .
This differs from https://github.com/TrinityCore/TrinityCore/commit/aa645683b8b25bfb35cb977678daf5c56c1531e6 because it includes a fix https://github.com/memononen/recastnavigation/commit/77ebf643531c90ea712b496e23c48f0b0671f43d which correctly extract tile connections when using rcMergePolyMeshes(), used by mmaps_generator.
MMAPs version is now set to 5.

Re-extract MMAPs using mmaps_generator , any old extracted MMAPs will not work.

Core/Battlegrounds: Fix invalidated iterator crash

Partially revert e1bee86ee6f5c3ab7b1da6d1b54c98c2851f11ec and restore 9ba3d07fc22864daa51b2faf327ac3336569e463 to store battleground queues as std::list instead of std::deque because deque::erase() invalidates all iterators.
