Standardize the naming conventions of variables

[ferdis]

I propose that we standardize the naming conventions of variables. By default, Swiftlet uses "User" named variables: it would be advantageous to rename them to "player".

renamed the issue to "Standardize the naming conventions of variables" so that we can keep track of not just this 1 case, but other cases where variables need standardizing.

About the coding structure as well as naming conventions I'd say we go for as much PSR-1 and PSR-2 as possible. This way we have a set of rules we must follow which makes the code clean and awesome.
