Support disabling default front matter and add support for Templater

[kelszo]

These changes should be completely backwards compatible. The goal of this pull request is to make Media DB more compatible with the Book Search plugin and other plugins. Additionally, to provide a more streamlined and unified way for templating.

Closes: #91

Changes:

• Use the file path when selecting templates (fallback to filename to be backwards compatible)
• Add an option to disable the default front matter. Instead the front matter from the template is used.
• Support Templater, including using the media object. See below.

Example of usage of changes:

movie.md (template)

I left some review notes that need to be resolved before I can merge this PR.
The major problem I see is that compromised data in one of the APIs can result in arbitrary JS being run on the user's computer.

[kelszo]

I have resolved all your comments.

I agree with the part about code execution. The simpler solution was to shift the heavy lifting and ensure reliability through the Templater plugin. Now, it adds a <%* block at the top (provided the user has the Templater plugin installed), allowing all subsequent Templater commands to access the media variable.

Please let me know if any comment that I marked as resolved is not satisfactorily addressed, and I will gladly make the necessary corrections.

[mProjectsCode]

This looks better :)

There is still one more thing that I would change.

Tie all the templater stuff to it's own setting so that the usage of templater is independent of the "Use default front matter" setting, This setting should mention that it needs templater and make the user aware of the security risk that comes with using it.

[kelszo]

Done! :)
