[LIBREPORT PATCH] make the dependency on recordmydesktop soft - related to rhbz#891512

[Jiri Moskovcak]

- also added a help text about installing it if it's missing
- shouldn't affect Fedora because the dependency is in spec,
  but on RHEL it can't be installed by default and user has to install it
  from EPEL
