Normally, Rebar runs eunit tests in the order the beam files are
stored in the file system (see rebar_utils:beams).  However, sometimes
it is desirable to run the tests in a different order (e.g. to
reproduce an error found on a build server).  For that case, it would
make sense to use the 'suites' parameter not just for selecting which
modules to consider, but also for choosing the order.

app_bin option was used by the install command which has been
removed in 51ed787.

zsh completion: fix typos

Add skip_deps=AppListSeparatedByCommas feature.

I agree it's a bit of a weird thing, but it's a reasonable and safe extension. When time comes to properly overhaul stuff, skip_deps should disappear entirely.

Add zsh completion script

This allows `rebar ct suites=abc` to consider all suites when
you have a rebar setup with multiple sub_dirs.

Previously, rebar halted after it could not find the suite in the
first dir. But the suite might be present in another dir (when
sub_dirs contains multiple dirs).

This commit makes it so instead of halting, it prints a warning and
continues with looking for the suite in the other `sub_dir`s.

Note -- This uses try/catch to cause the test to be skipped because
otherwise I needed to adjust the return values of 4 functions, the
code path is pretty deeply nested here. Otherwise the whole call chain
needed to be adjusted for this return value:

`run_test -> make_cmd -> get_suites -> find_suite_path`

IMHO, I think for exceptional cases like this it is fine to use throw;
specially since only the {skip} is catched and nothing else.

For enable to shell-completion in zsh.

Add support for minimum OTP versions

Revert arch string changes

When a DTL template includes other template files, those files don't need
to be compiled separately, and therefore can be given an extension different
from `source_ext` (such as `.dtli`) to avoid being compiled.  This fix
allows rebar to find included dependencies with names `*.dtl*` rather
than `*.dtl` and properly determine if a template file needs to be recompiled.
