Support for Older Bash Versions (3.2, 4.4, etc) - v0.4.0

Bash-TPL

A Smart, Lightweight shell script templating engine, written in Bash.

Release - v0.4.0

• Adds support for Bash versions 3.2+

Thanks to @flaix for pointing out that I inadvertently broke support for older bash versions by using constructs that were only available in newer versions.

I re-worked the code the also ran the existing BATS tests against multiple Bash versions: 3.2, 4.4, 5.0, and 5.1
