RandomFilePicker - v1.4.2

v1.4.2 adds a manual mode, and a filter to prevent accidents such as other scripts/executables/keywords.

-- Additions --

1. Manual Mode:
   Disabled by default.
   Allows you to manually set your search mode each time you run the script.

2. Filters:
   Can filter out extensions such as ".exe", or ".py"
   Can even filter out keywords such as "screenshot" or "wallpaper"
   .exe is filtered by Default

-- Fixes --
6. When search criteria is not specific enough, there was a chance for the script to open folders despite being told to only open files with extensions.
