[TEM #1] - Escape Arguments In Template Files

[sgoudham]

What's the Issue?

At the minute, arguments within template files are not subject to escaping. This ultimately hurts the user as the user may genuinely want to include {path} within their template file and not have it replaced by an argument.

Current Behaviour

Given template file foo.md

Article written by \\{author}

and article bar.md

{{#template foo.md author=bar}}

When the above example is compiled, the resulting bar.md looks like

Article written by \\bar

Expected Behaviour

Given template file foo.md

Article written by \\{author}

and article bar.md

{{#template foo.md author=bar}}

When the above example is compiled, the resulting bar.md should look like

Article written by {author}

Proposed Changes

Unfortunately, I'm not sure how to implement this behaviour without completely replacing the current replace_all() method from the AhoCorasick crate with another regex that is similar to the way {{#template ...}} is implemented.
