Fixed mathview so that it doesn't look janky on small screens.
Cleaned up MathView a little bit. The big changes are

1) It now supports latex editing.  Just add the class latexentryfield to a text area and it will make a button for a mathview latex edior
2) Added this mathview latex editor functionality to PGProblemEditor2/3.  It can be turned on and off by a config variable (which is not in the Course Configuration area)
Added the ability for mathview to work with essay answers.
Merge branch 'release/2.9' of https://github.com/openwebwork/webwork2 into mathviewups
Small tweak to make formatting on editor page look nicer
Added a more dynamic nav bar that can be collapsed or opened.  Starts collapsed on phones but can be opened.
Collapse button is not shown when there is no site nav
Fixed cursor position for intervals.

Mathview Upgrades -- The cursor is inserted in the correct position when inserting interval notation.
Fix 2 bugs with LB1: hide problem buttons would sometimes delete too many problems or go into an infinite loop, the tag widget would sometimes delete lines from the pg file.
Change OPL-update so that it uses Taxonomy2 which cross-lists sections of the library.  Also makes sure DBsubject/chapter/section are case sensitive.
Made some improvements to how more like me works.  Now if you hide a more like me it hides the table (if closed) and moves the more like me button to the new top element (if appropriate).
