Reworking window/game title tracking

[cr08]

Currently the script is written to check the foreground window upon stopping the recording/replay and use the title found in that moment for the rename (as documented in the README). This becomes problematic for example if you manually click Stop Recording in OBS as it will see OBS as foreground and label it as a Manual Recording. This means this script is really only viable with a hotkey or external tool such as a Stream Deck where you can stop recording with a game remaining foreground.

A potential fix may be to continually track the foreground window for the duration of the recording, logging this somewhere. We can keep this within the existing timing loop which defaults to checking every 15s. Upon stopping the recording, we have a couple of potential options:

1. Determine the longest running window logged during the session and use that for the rename.
2. Include all logged unique window names in the recording filename (may need to add in exceptions for stuff like browsers that can change titles based on the page)
   2a) Include the top <x> window names in the recording filename, count selectable by the user
   2b) Include all logged unique window names, excluding common 'Desktop' applications.
3. Determine a better way to detect applications in Python that can be tailored to focus on games, even if not in the foreground.

Optionally: Provide the option to the user to pull the stream title from Twitch using app credentials provided by the user.

I will not be supporting other platforms at this time since I am only familiar with Twitch and it's APIs. I will gladly take PR's for other services however.

If this option is added, I will likely have a dropdown of different 'behaviors' in the script dialog in OBS, ie: choosing to pull the stream title from Twitch OR locally monitor window titles and utilize whatever behaviors are chosen from the original issue notes above.

As far as the options above, I think option 2a makes the most sense and we can default the 'app count' to 1 so it only shows the single longest running app that session in the filename.

Additional thought came to mind to me this morning: Since not EVERYONE will stream and some may stream sometimes and just record other times, for sake of user-friendliness we may want to add conditions so that if the Twitch option is selected but no streaming happened, we fall back to checking windows?

I'm definitely up for further discussion on this.
