instance property names. This problem occurs even in class methods (in
addition to instance methods).

Tweak reading content-length to allow responses larger than 2GB

* ASIDownloadCache now strips trailing slashes from urls when building the key used to store the data. Now it doesn't matter if the request's url includes the trailing slash or not
* ASIDownloadCache now names all data-files with an .html extension. This allows ASIWebPageRequest to display frames and iframes with local content.
* Remove broken NSURLCache compatibility from ASIDownloadCache
* ASIDownloadCache now stores its data in the NSCachesDirectory instead of  NSTemporaryDirectory (Thanks to Dincho Todorov for pointing this out!)
