Move here-doc sources to separate files.

With the rest of the spec cleaned up, these clutters too much.
Handle the libssl/libcrypto 0.9.8/1.0.0, rewamp filtering.

We need to handle the deps for libcrypto/libssl. Install script
will resolve the 0.9.8 requires as 1.0.0 iff 1.0.0 is present
and 0.9.8 is *not* present during build. This is too complicated
to fix, so we just add some hard links after 'make install' to
always use 1.0.0 according to mysterious entry in changelog.

Current filtering is broken. It Provides: libcef.so, making it possible
for other apps to link to that library. It also turns off the
dependency generator which makes zypper happily install package
with all sorts of dependency errors unless we state all of them
explicitly (how has this ever worked?).

Removing complete filter solution, using upstream builtin filtering
instead. Requires us to add som manual Requires: for symlinked deps
which not are picked up automatically. No solution is really optimal
here, but this is the best I have found out so far.
Remove %mandriva  and %fedora conditionals.

The mandriva are not maintained and probably little help should
someone step up to make a mandriva spec. They also adds clutter
somewhat. For the fedora ones, there is already a spec in much
better shape.
Establish a proper src.rpm (issue #3).

Although we havn't the sources, it makes sense to package a complete
srpm which can be used on any supported architecture.
Updating to 0.9.0.
Removing 0.8.8 RPATH fix

The 0.8.8 release contained a bad rpath, which required code to
handle (i. e., basically accept) it. Since the 0.9.0 does not
have this bad rpath the checking can be restored to the sane
defaults.
Updating install-spotify.sh and installation package.

Major update. Don't require spec file to be installed, download it instead.
Use set -e instead of home-brewed safe-run. Use rpmdev-setuptree to create
a personal build environment if needed (i. e., so user can build without
root privileges). Only require root privileges to install/uninstall. Use
spotify-make to download .deb packages. Use rpmdev-spectool to download
other sources. Don't hardcode locations to %_srcdir, %_topdir etc.

As a consequence of above, the spec is excluded from the spec file and
the README updated.
