daily generated Kea developer documentation

[Jeremy C. Reed]

Just to let you know, the Developer's Guide is generated daily and is at 
http://git.kea.isc.org/~tester/kea/doxygen/

(I did some cleanup so moved the old bind10 files to different 
directory.)

In addition, the administrator documentation for the latest
development version is also generated daily. It is available at:
http://git.kea.isc.org/~tester/kea/guide/

This also includes the logging messages descriptions.

(I will have it include the manpages in HTML format later, like I was 
doing only at snapshot and release times before.)
