Upgrade TinyMCE to 5.0.16

Description

We're using TinyMCE 4.3.2, but TinyMCE is up to version 4.6.7 as of the creation of this issue. Our version is almost two years old, so it's a good idea to upgrade to take advantage of bug fixes.

The version used in the merged pull request is 5.0.16.

Testing:
Refer to https://wiki.transformativeworks.org/mediawiki/Testing_the_Rich_Text_Editor.

Retroactive testing notes:

  • Check that TinyMCE does not switch to a more limited mobile version on mobile devices ().

  • Check that TinyMCE does not override the browser's context menu ().
