Releasing debian version 0.1.17-2.1.

patches/02-keep_source_when_copying.patch: keep source when
cut/pasting a directory across filesystems, avoiding data loss when
the copy fails. Next upstream really fixes #593607, but this
work-around downgrades its severity from critical to normal in wheezy.
Releasing debian version 0.1.17-2.2.

debian/patches/03-automake1.12.patch: Apply patch from upstream to fix
automake errors. (Closes: #713194)
Moving package to priority optional.
Removing cache files if no other gio module is left on purge (Closes: #659925).
Adding manpage for libfm-pref-apps.
Updating GPL blurbs in copyright file.
Merging upstream version 1.0.
Adding myself as co-maintainer.
Adding valac to build-depends.
Using upstream manpage for libfm-pref-apps instead of local version.
Renaming libfm1-dbg to proper unversioned name libfm-dbg.
Bumping soname to 3.
Enabling debug symbols.
Updating symbols file for upstream version 1.0.
Enabling hardening.
debian/rules: Enable parallel building

See `man dh` and `man dpkg-buildflags` for more information. The user
has to enable for example in `/etc/dpkg/buildflags.conf` how many jobs
can be build in parallel.
Merging upstream version 1.1.1.
Correcting dependency for libfm-data: Replaces to Conflicts.

the 'Replaces: libfm0' on libfm-data doesn't enforce removal of libfm0
nor libfm1 but both libfm0 and libfm1 contain the same files as the
libfm-data package so 'Conflicts:' was added instead.
Corrections for symbols files.

Files debian/libfm-dbg.symbols and debian/libfm-dev.symbols have no
usage. Files debian/libfm-gtk3.symbols and debian/libfm3.symbols has
wrong symbols.
Updated debian/libfm3.symbols and debian/libfm-gtk3.symbols to the
symbols and required versions up to libfm 1.0.1 version.
Adding libfm-gtk-data package - libfm-gtk3 will crash without it.

Without libfm-gtk-data (library independent) package libfm-gtk will crash.
And there we have two choices:
1) to have libfm-gtk3 dependent on libfm-gtk-bin;
2) to add libfm-gtk-data package.
libfm-gtk-bin package contains optional binary application
which never required nor somehow related to libfm. The only
relation is libfm-pref-apps application is linked against libfm.
Therefore have libfm-gtk3 package to be dependent on it is
completely wrong and inappropriate.
So only good choice is to add the libfm-gtk-data package.
