Add support for .bats.sh convention tests

[ArturGajowy]

IntelliJ IDEA highlights each end of a Bats test case with an error marker when using .sh syntax highlighting, which makes Bats adoption much harder in some teams. Thus the feature proposal for supporting .bats.sh test files with a convention-based test discovery. From README.md:

---

Bash-compatible convention syntax

If your tools don't have built-in support for .bats syntax, you can
still use Bats with its support for .bats.sh convention tests. Each
function declaration starting with the funciton keyword is going to be
converted to a Bats test. For example, running the following test file:

#!/usr/bin/env bats

function test_using_bash_convention_syntax {
  result="$(echo 2+2 | bc)"
  [ "$result" -eq 4 ]
}

will output:

$ bats bash_addition.bats.sh
 ✓ test_using_bash_convention_syntax

1 tests, 0 failures

---

Test suites

You can invoke the bats interpreter with multiple test file
arguments, or with a path to a directory containing multiple .bats
and / or .bats.sh files. Bats will run each test file individually and
aggregate the results. If any test case fails, bats exits with a 1
status code.

@sstephenson any thoughts on that? Should we merge or should we close?

@sstephenson kindly ping :) What's your opinion on this proposal?

Hi! sorry, didn't notice :) Can you add a heads-up to the README.md?

I would also like that, but I think only @sstephenson can do that.
