Rework of MineCube.cs and further improvements to CalculatePath() (#2014)

Browse source 
* Add function to determine if the client is executing a walking process
* Add comments
* Remove test bot entry
* Add funtion to approach a block as close as possible
* Add funtion to approach a block as close as possible
* Add funtion to approach a block as close as possible
* Add comment to function in McClient.cs
* Improve concurrency and reduce potential calculation power
* Apply code suggestions
* Apply code suggestions
* Improve CalculatePath() function to allow approaching
* Fix typo in MinecraftClient/ChatBot.cs
* Add comments to Chatbot fucntion
* Add break to for loop to exit quicker
* Allow to give a maxOffset to the goal
* Comment the sample bot again.
* Add parameter for calculation timeout
* Remove TestBot again
* Implement timeout in Chatbot class
* Remove test commands
* Update comment in Chatbot.cs
* Set timeout to default 5 sec
* Change order of parameters back
* Add suggested improvements
* Move task and fix missing methods in .NET 4.0
* Create switch for tool handling
* Remove unused function
* Improve movement
* Improve performance of CalculatePath()

 - Replace Hashset OpenSet with a Binary Heap
  - Temporary remove maxOffset / minOffset features
 - Round start location for easier calculation
 - Add 0.5 to each location in reconstruct path to avoid getting stuck
    on edges

* Add diagonal movement
* Remove direct block movement
- causes kick for invalid packet movement if moving on the block you are
  currently standing on

* Floor start in A* and improve diagonal walking check
* Add helperfunctions to McClient.cs
* Prevent client from falling into danger
* Add comment to function and remove dependencies
* Add comments
* Remove debug settings
