General re-write of Home.md

* Re-written opening blurb.
 * Moved 'Supported platforms' to be second section.
 * List of supported websites and tools, which doubles up as a glossary
 of the short names used to refer to them later.
 * This allowed simplifying (no duplicate links to maintain) the list of
 functionality.
    * Added 'click' functionalities to the list.
    * Closed with a statement about third-party plugins.
 * Simplified 'Click on' for Ship/System/Station by not mentioning the
   current choices.  No need to update if the list changes.
