x11-toolkits/attica: Change the location where we install its headers.

In preparation for the upcoming KDE Frameworks 5 and Plasma 5 ports, install
attica's headers into include/attica/attica instead of include/attica.

Users of attica reference the headers in the code with
    #include <attica/foo.h>
which means the compiler is passed -I${LOCALBASE}/include for the headers to
be found.

The KDE Frameworks 5 version of attica installs the headers into
include/KF5/attica, so depending on the other of the arguments the compiler
can end up being passed
    -I${LOCALBASE}/include -I${LOCALBASE}/include/KF5
leading to the wrong attica headers being used instead.

By changing the header location, we make sure one passes
-I${LOCALBASE}/include/attica to use the attica 0.4.2 headers.

The original idea and code came from Tobias Berner <tcberner@gmail.com>,
with further improvements from myself.

While here, add some comments explaining why some sed calls are made in the
post-patch target.

Last but not least, audio/tomahawk had to be patched for the attica headers
to be properly found now that they are no longer in ${LOCALBASE}/include.
The patch itself contains a larger explanation of what had to be done. All
other ports depending on x11-toolkits/attica work fine without any changes.
