Performance & Playlist Improvements

If the installer errors on exit or if the app doesn't get installed, please download the pre-installed folder (Gizmo Music.rar) and place it in C:/Users/USER/AppData/Roaming/Gizmo/. (And make a shortcut to the exe inside it, lol)

This update includes:

• Current playlist will be autosaved,
• If a playlist is saved, the song listened to last will be loaded at the exact time it was left at,
• Huge performance improvements (includes loading data / loading screen going away really quick),
• Key Controls (Left/Right Arrow keys in the main window will go back/skip 15 seconds in the song; 0 in the main window will restart the song; Up/Down Arrow keys will go through the playlist in the playlist window; 0 in the playlist window will go to the first song),
• You can now drag a folder full of songs into the playlist window to load them all at once (works with another folder inside),
• When the playlist window overflows with songs, it'll show a scrollbar,
• Audio Visualizer toggle will now actually disable the visualizer script,
• Playlist song entries will now have their artwork next to them,
• Title quotation and truncation improvements,
• Uninstaller icon should have its own icon now,
• Updated to Electron v2.0.13,
• Changing the time on the progress bar will now work when paused,
• Fixed data toggles miss-toggling,
• And a ton of other bug fixes that I'm too lazy to mention.
