Merge jmckinstry's Pull request (#15)

- Look and naming (tried to unify things a bit)
- .gitignore for ignoring files we don't want to track
- Moved APPLICATION_ID to somewhere that could be made safe for Github without making life harder
- Fixed the bug with showing the wrong play state when loading FB2K
- Fixed the bug where tracks with really long titles would cause janky behavior
- Added unencumbered images if folks didn't want to make their own
- Added DEBUG_CONSOLE_PRINTF calls for debugging
- Removed rate limiting that was already handled in Discord's library code
- Removed UnicodeToAnsi as it was unused
