Improved scope and block management. Implement a max depth for scope aswell as a check if a new scope is needed in block calls.

Identifiers can now reach variables in the scope. However not currently working with arithmetic operations. Think the AST for that one has priority before variable lookup

Messy but functional code for bot calls and method calls. say [1,2,3].length(). Will need to be refactored.

Adds variable declaration
