log4r 1.1.4 released

credit:C G-K
Now available, the 1.1.4 release of log4r (See: http://log4r.rubyforge.org or gem install -r log4r)
In this release I added code to implement Nested, Mapped and Global Diagnostic Contexts that work the same as they do in Log4j, see NDC/MDC on http://onjava.com/pub/a/onjava/2002/08/07/log4j.html?page=3 for a deeper explanation. Copied concept of GDC (global name for a program) from an older branch of log4r.
Also fixed in 1.1.4:
Logger.new was not thread safe, it is now
RollingFileOutputter created spurious non-numbered files, now fixed
Errors about null at end of yaml configuration files, now fixed
