Don't rename "id" and similar variables #158
Description
Even though it's also a type name and confuses the code coloring in Xcode, "id" is a valid variable name in Objective-C and I've used it quite a bit. This should be even less of a problem in Swift because it's not a type name, but Swiftify renames my "id" variables to "anId":
input: NSString *id = @"foo";
output: let anId = "foo"
expected: let id = "foo"
demo: http://swiftify.me/i8a32t
Similarly:
input: for (NSString *id in sortedEvents) {}
output: for anId in sortedEvents {}
expected: for id in sortedEvents {}
I noticed the same behavior with variables named "url" being changed to "anUrl." I think in both languages, "URL" is a type, but "url" is a valid variable name.
