Add Buffersize in BufferedInputStream constructor

[palamccc]

This is a minor, feature request. While creating BufferedInputStream by its constructor, buffer size argument is missing. Because of that, android prints out following warning in logs. When i cache lot of images, following warning is filling up my log window. Please add buffer size argument to the constructor.

08-22 08:55:07.558: I/global(1158): Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required.

Thankfully current versions of Android don't have that annoying warning!
