* share/dtf-controller/results-stats-templates/html.tmpl: Fields
of the result table are now hyper-linked with particular results.

* controller/bin/dtf-controller.in (subcommand): Generate
stdout and stderr files separately.
(child_task): Generate '*.err' and '*.out' logs for subcommands.
Call dtf-run-remote with --distro/--distro-version options.  Call
the dtf-result-stats finally and save its output to results.html.
(main): Simple debugging info and comment adjusting.
* controller/libexec/dtf-commit-results.in: Tak three arguments
now.
* controller/libexec/dtf-result-stats.in: Better read the
'tester/run' output.
* controller/share/dtf-controller/ansible/playbooks/fedora.yml:
Run the 'run --force' instead of 'run' on remote host.
* controller/share/dtf-controller/results-stats-templates/html.tmpl
React on exit_status 2.

Move 'results_stats' and 'commit_results' binaries into libexec
and adjust appropriately.  Also html template is now in
$pkgdatadir.

* .gitignore: Add tags/ChangeLog generated files.
* README: Just some random notes.  Needs to be rewritten anyway.
* controller/.gitignore: Add newly 'make'd files.
* controller/Makefile.am: Generate libexec/bin files.
* controller/commit_results: Move to controller/libexec as
dtf-result-stats.in.
* controller/configure.ac: Also substitute resulttemplatedir.
* controller/etc/dtf.conf.d/config.sh.template: The DTF_DATABASE
was misleading - use rather DTF_DATABASE_DEFAULT.
* controller/libexec/dtf-commit-results.in: Moved from
controller/commit_results.
* controller/result_stats: Moved to
controller/libexec/dtf-result-stats.in.
* controller/libexec/dtf-result-stats.in: Moved from
controller/result_stats.
* controller/result_templates/html.tmpl: Moved to
controller/share/dtf-controller/results-stats-templates/html.tmpl.
