Fixes ["Fishing Speed Too Slow"](https://forum.cuberite.org/thread-3175-post-29000.html#pid29000).
Interestingly, the constants @NiLSPACE points out are actually correct:
```cpp
(Random.RandInt(100, 900) - static_cast<int>(a_Player->GetEquippedItem().m_Enchantments.GetLevel(cEnchantments::enchLure) * 100))
```
100 to 900 ticks is the correct timing of 5-45 seconds. However, the timer is only updated when the floater is in the water and the server side position was actually bobbing in and out of the water. This meant the timer took ~2-3x longer than it should.
With this change the floater position is always in the water and so the timer works as expected.
* Made BroadcastSoundEffect take vector parameters.
* Added docs for new vectored methods
* Removed old code
* Fixed lua warnings
* Made old BroadcastSoundEffect not an override.
* m_Block to m_BlockPos, used Vector3d constructor where prettier.
* a_Block to a_BlockPos
* Changed thunderbolt a_Block to a_BlockPos
This was mostly done automatically and then visually inspected for obvious errors.
All //-style comments should have a 2-space separation from the code, and 1 space after the comment sign.
