First Full Release (#1)

* Commit default app. * Add future strings. * Start trying to make changes. Laptop is very upset at Android Studio, or vice versa. * Still nothing working. About to restart and not choose Empty Activity, do everything from scratch. Unsure if it's a laptop performance issue or if the default app really comes broken. * Builds successfully now, but still has 21 errors and 3 warnings. Very weird. Emulator will not run, will try a different laptop. * It works!! Still needs some UI enhancements like the buttons being fixed sizes and looking more like a grid but it's completely playable with a friend and may not even have any bugs. ;) * Made the board not shift around when letters are added. Still need to fix the clear board button from shifting all contents up. * UI is done, game is still playable. AIs not functional yet, Random is coded but radio buttons not working. * Reorganization. Turning on the AI logic freezes up the interactive preview and emulator is not working so can't do a real test yet. * Fixed all the warnings. Toasts might work now but preview freezes up when trying to test them. * Everything besides the weighted opponents seem done. Preview is really unhappy. Need to get a device connected. * Got the theme working properly with dark/night. Starting to generate debug APKs for testing on phones. * More work on the random AI after realizing what it was doing. Making the bottom buttons more generic, controlled via strings xml. Layout improvements. Fixing the AI's turn taking ability. Shortening Toast. * Large refactor and some bugfixes. Random AI is working in the preview. Toasts and radio buttons are not, but they do on a real phone. All warnings fixed. * Fix toast having the wrong opponent piece. * Fix radio button areas not all being clickable. Increase link font sizes. Change URIs to be exactly how the browser shows them * Make the toggle switch text clickable. * Game is finished!! Can't find any bugs either. * Change TODO to TBD so Android Studio does not complain. * Force portrait mode. Game is completed, all AI have been tested to work as expected. Cannot find any combinations to crash the app. * Add app art. * Ignore keystores. * Be more specific about keystores. * Don't include release files. * Add information to README. * Change X and O formatting. * Fix direct download URI.
