Migrate to new EJS CDN, and save state tweaks (#264)

* Saved game icon now displays on game cover art in library

* Fixed casing error on save state download icon

* Migrate EJS from submodule to 7z download during docker build

* Updated README and gitignore

* Resized library search buttons

* Export to JSON now triggers the download rather than display of a formatted platform map
