Added showIntSize/getIntVal to Base code
Added define{Empty,Typed}Var to Environment
Adjusted eval behavior for properly-typed variable declaration
Set parseLiteralValuesRef assignment back to normal

Not planning on leaving the expression parsing in there anyway
Pointed declaration/assignment parsers to use parseLiteralValues

Now the parsers for these things can take types other than strings.
Pointed readExpr to use parseExpression instead of parseLiteralValues
