- Improved the `enum` operator. Now it supports explicit values.

Example:
	enum {Apple, Banana, Cherry};   # Numbered 0 through 2

	enum {
	    Apple=3,
	    Banana,         # gets the value 4
	    Cherry="a",
	    Orange,         # gets the value "b"
	};

- Improved the parsing of init variables and function parameters. Now they can include comments and can extend on multiple lines without any problems.
