Patch to allow seperate build directory

[Dibblah]

This patch allows the following to work:

mkdir ~/mythbuild
cd ~/mythbuild
/usr/src/mythtv/configure
make
make install

• the source directory is completely seperated from the build directory. The source directory is not modified during the build.

It's fairly hacky, but consistently so:

qmake, when it include ( )s a file, changes into the directory of that file first. This means that it's not possible to easily centralise these changes.

Headers do not seem to get pulled in from the VPATH if they're located away from the current build directory - Hence the modifications to the INCLUDEPATHs.

A couple of #include "mythconfig.h" needed changed to #include "config.h" to make picking up the configuration from the build directory easier.

If you are compiling in the same directory as the source, this change has no effect at all.

It has only been tested on x86. I can't see how it'd break other architectures, but it is probably worth mentioning.
