qdoc: Make example file names unique

To avoid duplicate files for examples, the files
are named this way. Suppose you have an example
called mandelbrot. The example is in a subdirectory
named mandelbrot, and there is a \example command
somewhere like this:

\example mandelbrot

In this case, the mandelbrot example is in the QtCore
module. Then the name of the example page will be:

"qtcore-mandelbrot-example"

...and the names of the example files will be:

"qtcore-mandelbrot-main-cpp.html"
"qtcore-mandelbrot-mandelbrot-pro.html"
"qtcore-mandelbrot-mandelbrotwidget-cpp.html"
"qtcore-mandelbrot-mandelbrotwidget-h.html"
"qtcore-mandelbrot-renderthread-cpp.html"
"qtcore-mandelbrot-renderthread-h.html"

qdoc: Fix the qdoc \include command

qdoc's \include command now works as expected.
This command is only for including a file that
contains qdoc comments that contain qdoc commands
to be processed by qdoc. The file to be included
should have the .qdocinc suffix, although qdoc
will accept any suffix now. The file must be in
one of the directories specified by the sourcedirs
variable in the qdocconf file.
