Added support for environment variables to 'templates' module. (#1035)

Browse source 
* * Added support for environment variables to 'templates' module.

* Fixed flaw in test caused by environment variable ordering during testing on CI.

* Updated some local variables to camel-case.

* Reverted changes to replacer as environment variables are processed elsewhere.

* Removed PrintEnv functionality in favour of documenting using template range.
