Inconsistent shebang usage in bash scripts

[Jesse Pretorius]

Currently the shebang in each bash script is inconsistent.

In order to be more consistent, and also account for different environments and platforms, the use of
#!/usr/bin/env should be implemented as the shebang for all bash scripts in the environment.
