Countdown 1.1

Fixed several issues with the previous version and made it more obvious when the app is working and when it's idle.
No changes to the actual word-finding logic, so an upgrade isn't required if you are fine with v1.0's quirks.

Executable made using pyinstaller and it should work fine on systems without python installed.
