[jcifs] jcifs-1.2.11b released / SID Resolution

[Michael B Allen]

This release significantly expands the SID and ACE classes by using the
new MSRPC infrastructure to resolve SIDs to their associated account
names. A new SmbFile.getSecurity() method has been added which if called
with a boolean value of true will resolve the SIDs returned within the
ACE[] array such that SID.toString()/getDomainName()/getAccountName()
will return text about the account associated with that SID suitable for
display to users (e.g. MYDOM\alice, SYSTEM, etc). Documentation for all
associated methods and classes has been added.

A fix for a NullPointerException within DcerpcPipeHandle has been applied.
