Snap package improvement

[soumyaDghosh]

@johnfactotum I found a lot of issues, on the snap package. It's certainly my fault that I didn't check them. But, there are some issues, which can be fixed. But, there are somethings I am seeing in the app that seems to be unrelated to the snap. Like, when I open the font selector, it lags a lot. Also, we can make the snap look for fonts in .fonts, .local/share/fonts, but they have to be manually connected/allowed by the user. Also,

Wrong type undefined; string expected

I suppose this would happen if the book has no title. Not really related to Snap.

are these access necessary?

Not sure what those are. I think those warnings are from WebKitGTK. It only happens for Snap.
