Metacat

Add authorization functionality

Change sanparks skin to log in with browser session instead of metacat client session so session can be validated on other pages.

Add user name to SessionData object

use arguments for the main() method - hardcoded URLs and test docids are poor form

return InputStream instead of Reader in the MetacatClient read() and readInlineData() methods. Can now handle binary data
