Update WanderingInnParser Titles

[bendur]

This PR fixes the titles for The Wandering Inn chapters that have started picking up an h2 for comments being disabled instead of the chapter title.

It modifies the title selector to be prepended by div.post.

Example page: https://wanderinginn.com/2017/03/03/rw1-00/

Tested on Firefox with several volumes.

Fixes #2528

@bendur do you want to add yourself to the "contributors" section of packages.json and updated the "Credits" section of readme.md with your name?

[gamebeaker]

@bendur i don't get the error "Comments are temporarily paused while we perform maintenance. Thank you for your patience." as described in the issue.

Can you please share an URL where this issue happens.

[bendur]

@gamebeaker Sorry, I should have done a better job with the replication info.

To see the issue:

1. Start with the table of contents.
2. Open the extension.
3. Select just chapter "1.00" (if you just want a quick test).
4. Pack EPub.
5. Open the resulting file, the chapter title should be "Comments are temporarily paused while we perform maintenance. Thank you for your patience."

@bendur
Apologies, easiest way to add this was to copy it. Due to other MR update the package.json file.

Thank you for your contribution.
