First Pass at E17 / E19 Dependency Fixing, Updated ePad

Updated ePad to include all recent fixes and improvements.

Fixed some broken dependencies and conflicts.

Removed temporary files that had gotten accidentally included.

Made a first pass at treating the Enlightenment / E17 / E18 / E19 dependencies and conflicts consistent by always using Enlightenment as the general term and E1[789] for specific releases. This was sometimes done before, but not always, and in a few cases Enlightenment was treated the same as E17.
