[REQUEST] Stop looking for store page when a game or app doesn't have one anymore

[y0LAs]

Is your feature request related to a problem? Please describe.
The app is terribly slow because it hands for too long on games that do not have a store page anymore.
These games or apps are many : I have 189 in my library of 4257 games.
Depressurizer is "not responding" and heavy on the CPU for long minutes.
On the logs, we see that it's just not finding store pages for many games.

Describe the solution you'd like
There should be an autoflag function for these games to not be searched again. Or a better timeout policy.
