Add support for JavaScript "get" and "set" keywords

JavaScript has support for getters and setters via get() and set() methods since a long time now and it's supported in many major browsers. It'd be nice if Aptana Studio could support those keywords as well.

Example script:
var object = {
someInteger: 4,
get someValue()

{ return "4"; }

,

get integer()

{ return this.someInteger; }

,

test: function()

{ return 1 + this.someValue; }

};
