datatype macroquest: add BuildName

[martinlindhe]

I also would like to ask about the new data types. How do they help, and what is the difference between eg. MQFloat and number (both are float?) and MQString and string (both are string?

MQString and the other new types are aliases not actually new datatypes. They are found in the alias.lua file. Many of the MQ primitives on datatypes look like members but are actually a function in Lua. Other MQ userdata types operate in two ways, often returning an object if called in the middle of a "dot train".. TLO.Me.Spawn. = > returns a spawn object whereas TLO.ME.Spawn() returns a string. To the Lua Language Server, there is no difference between Spawn and Spawn() so you have to write a definition that is spawn | fun(): string|nil, meaning this returns a spawn object, or a function that can return a string or nil. The aliases provide a way to capture this repeating pattern and just write it once.
