* Initial commit. Untested * various fixes Core functionality confirmed working: - Iframe injection into steam client - Plugin fetching from the iframe - Plugin opening * Added function to fetch resources from steam * Improved injector module, added server-js communication - Injector module now has methods for better lower-level manipulation of the tab debug websocket. - Our "front-end" can now communicate with the manager (2-way), completely bypassing the chromium sandbox. This works via a dirty debug console trick, whoever wants to know how it works can take a look at the code. - Added utility methods file, along with an implementation of the aiohttp client that our "front-end" can access, via the system described above. - Added js implementations of the communication system described above, which can be imported by plugins. * Added steam_resource endpoint * Added basic installer script * retry logic bug fix * fixed library injection, event propagation, websocket handling - library is injected directly into the plugins as well as the plugin list - resolveMethodCall is implemented in the plugin_list.js file, which in turns calls window.sendMessage on the iframe to propagate the event - websocket method calls are processed in their own tasks now, so as not to block on long-running calls.
