Added Options -Indexes to prevent folder inspection when no index is present.
Added getLoadedVisual that takes a string and returns the visual (there can only be one) with that name or undefined if none was found.

Added addStylesheet method that loads a css stylesheet contained in the visual folder. Also the visual keeps track of the stylesheets in an array. The items in the array point directly to the DOM element referencing the stylesheet.
Format(visualParser): small formatting changed and update to the last modified date.
Refactor(admin): removed static reference to visualParser in the admin class. visualParser is referenced directly outside of the class. This may be a temporary change.
Adding entrypage.js to this commit. It did not get included with a previous commit for entrypage.ts.
