Fix for the formatting issues with bullet points for exported docx plans ...

when viewed in an old Word editor.

The fix follows the solution suggested in  the HtmlToWord bug "List item
bullets corrupted in Microsoft Word"
https://github.com/karnov/htmltoword/issues/73 suggested by David
Verhasselt @dv.

Changes:
   - Firstly, removed earlier attempted fix in commit
     5ef7e05 (Fix for format issues for
     bullet points in Plan docx exports).
   - Made a copy of Htmltoword (1.1.0) xslt stylesheets functions.xslt
     and numbering.xslt and made changes suggested by https://github.com/karnov/htmltoword/issues/73
   - Prepended the Htmltoword library XSLTHelper method xslt_path() in
     config/initializers/htmlto_word_xslt_helper.rb. This method ensures
     the Htmltoword library picks up the changed  numbering.xslt template instead of
     the library's version.
   - pinned version of htmltoword to 1.1.0

Added functionality to give warnings when links open in new windows. ...

The solution is based on the recommendation in "Techniques for WCAG 2.0" section
"G201: Giving users advanced warning when opening a new window":
"Example 2: Using CSS to provide a warning before opening a new window"
(cf., https://www.w3.org/TR/WCAG20-TECHS/G201.html)

Changes:

- any link in the views with target="_blank" has had css class "has-new-window-popup-info" to the link together with the span   <span class="new-window-pop-info"><%= _('Opens in new window') %></span>.
- The javascript script externalLink.js is used for external links that don't have the target="_blank" in the view.

Fix for issue #2175.

Fix for making links have a higher color contrast to other text in blocks. (#2192) ...

The changes were based on the article  https://www.viget.com/articles/color-contrast/

Changes:
 - Link color has been  changed from #337ab7 to #107896.
According to https://webaim.org/resources/linkcontrastchecker/?fcolor=000000&bcolor=FFFFFF&lcolor=107896 (the "Link to Body Text" ratio is 4.14:1 and passes WCAG A test and "Link to Background" ratio is 5.06 and passes the 5.06:1 which satisfies WCAG AA test.)
