Update distribution info for docs

New server hosting the docs, new path on disk.
Unused import.
ExcpetionHandlingIterable no longer uses Unsafe.

It was an ugly hack before, and it's still an ugly hack, but now

checked expceptions through the Iterable methods.
Adds a BreakableFileSystemAbstraction and uses it for TestDirectMappedLogBuffer.

Adds BreakableFileSystemAbstraction which is a FileSystemAbstraction that can
 break in highly customized and interesting ways.
Adds a test in TestDirectMappedLogBuffer which shows how things can break
 when DMLB is reused after an exception in writeOut(). This test rightfully
 breaks and is Ignored.
Remove reference to webadmin, now that neo4j-browser is the default web interface.
