Fix LIST YAMLParseError bug

[ltctceplrm]

See issue #181

Note that the correct template in this case becomes actorsList: {{ LIST:actors }} without any quotes around the template!

Seeing as #250 was posted recently I thought I might improve the PR a bit by adding a fix for this as well

This adds support for wikilinks in templates with an important note: The frontmatter does not accept wikilinks in comma separated values and would create invalid yaml so I split up ENUM and LIST into ENUM, ENUMYAML, LIST and LISTYAML. ENUMYAML ignores the requested wikiquotes and just outputs the comma separated values without any wikiquotes.

So you've got two options for the YAML:
actorsList: {{ LISTYAML:[[actors]] }}

actorsList: 
  - "[[Andy Lau]]"
  - "[[Tony Leung Chiu-wai]]"
  - "[[Anthony Chau-Sang Wong]]"

actorsEnum: {{ ENUMYAML:actors }}

actorsEnum: Andy Lau, Tony Leung Chiu-wai, Anthony Chau-Sang Wong

And two options for the body of the note:

{{ LIST:[[actors]] }}

  - [[Andy Lau]]
  - [[Tony Leung Chiu-wai]]
  - [[Anthony Chau-Sang Wong]]

{{ ENUM:[[actors]] }}

[[Andy Lau]], [[Tony Leung Chiu-wai]], [[Anthony Chau-Sang Wong]]
