Sanitize Input (GSI-900)

[TheByronHimes]

This update will run html.escape on all the values made available to the templates. With the example template, only the name and body are injected, but the other values are accessible to the person writing the config. Therefore, all in the payload dict are escaped.

Bumps version to 1.1.2

Also refactored the _construct_email method because the plaintext and html part constructions were redundant.
