Added section 5.1.2.2 "The Anjuta Plug-in" into the Poky Reference Manual.
This section consists of sub-sections 5.1.2.2.1 "Setting Up the Anjuta
Plug-in", 5.1.2.2.2 "Configuring the Anjuta Plug-in", and 5.1.2.2.3 "Using
the Anjuta Plug-in". This information was in the original Poky Handbook
but had been removed by me since I thought it was not going to be supported
for the 0.9 Yocto Release. It has now been restored with a note indicating
that Anjuta will not be supported post 0.9 release.
I did some general text editing in each section for readability.
