New Revision: 1006220

URL: http://svn.apache.org/viewvc?rev=1006220&view=rev
Log:
SHIRO-196 - Ensured StringBuilder instead of StringBuffer was used where possible.  One method
chould not be changed without breaking backwards compatibility and was flagged as deprecated
to be changed for Shiro 2.x.  Added RELEASE_NOTES.txt as a place holder for developers to
jot down notes while working in source code.  See the file for more information on proposed
usage.
