Oring should not be done with old status,
as it will always return failure.

Behat parallel run if executed together
then selenium might fail to launch browser
and timeout. It would be nice to have a
custom delay between the start of each process

Before this patch behat_dataroot for parallel runs
were created at same level as ->behat_dataroot
After this patch, it will be created 1 level under
->behat_dataroot with BEHAT_PARALLEL_SITE_NAME
prefix and run number as suffix. This will allow
common files as test enabled and parallel run info
to be saved in parent directory and access it easily.

run.php should only be used for running behat
before this patch if tags were passed, then behat.yml
was being re-written with features havings tags.
As this is not ideal, this option is now removed and
features with tags will be optimally split
by init.php when --optimize-run option is passed

As https://bugs.php.net/bug.php?id=71448 is
not going to get fixed, we need to declare tick

Adding a replace with run process in profile
should be allowed

Exit status should contain pass/fail information
of each run it is executing. Every bit of status
will have information of pass/fail status of parallel
process

This config will be supported to avoid broken configuration
in future. As this is limited, we need will still use
->behat_config to set config values which can't be set by
behat_profiles

1. Parallel run without feature should exit with success
2. Updated exit codes to be more clear for each process
3. Fixed wwwroot and dataroot while executing with tags
4. Added support for running scenario/feature
5. Added support for or'ing tags
6. Added support for running single behat site
7. Fixed wrong example in help
8. Use parallel run only when parallel > 1
9. Exit showing behat site is not installed
10. Exit with error, if not a valid option
11. Added usage in help to explain how to use command
12. run.php should be able to run from any path
13. Pass all arguments to single run

This solves some minor annoyances in the run.php script:

A) profile is checked properly, independently of everything else.
B) cli tags get precedence over profile tags.

Indicentally, this also causes run.php to support both profile and
tag in command line together. Previously the use of profile did
invalidate the use of tags.

1. Create behat datadir within behat_dataroot not at same level
2. Define suffix for link and not use hard-coded values
3. Renamed ns_parallel to run.php
4. Rename variables to best understand them
5. Added support for each run to specify db, prefix, rerun and profile.
6. Showing number of steps in each line of parallel run.
