APDL-Mode 20.5.0: Help for get- and parametric functions

• Browsing the help on keywords (C-c C-b) is now working for get-
  and parametric functions (additionally to all APDL commands and
  element names).
• Line numbers in the Variable Buffer (C-c C-v) are now links to the
  respective position in its APDL Buffer. Clicking with mouse-2 on
  the numbers is displaying the definition in the APDL Buffer.
• Added license overview with Ansys license feature descriptions to
  `apdl-license-status' (C-c C-l).
• Added a menu entry for browsing the main Ansys online help page.
