Simplify and speed up expr
*: Reuse the ParseTokenList/ScriptToken machinery for 'expr'
*: This is simpler than managing separate opcode/obj arrays
*: expr opcodes are now in the same namespace as token types
*: expr identifies int and double during parsing
*: Move the 'while' common expr optimisations into Jim_EvalExpression
*: Add a special trueObj and falseObj to help with these boolean optimisations
*: Add lazy versions as the byte code is created instead of at the end
*: Avoid repeated conversion attempts to int
*: Once an object fails conversion to int and succeeds
conversion to double, invalidate the string rep
so the int conversion attempt no longer happens
*: Also, avoid converting non-ints to int in expression optimisation
*: No need for a string token for SEP and EOL tokens
*: Fix shimmering of int -> double
*: When an int shimmers to a double during an expression,
remember that the value was originally an int (via a new
type, coerced double)
