Add anonymous usage analytics about presenter HOT 8 OPEN

Can we define a solid list of metrics that we might be interested in?

Here are a few ideas:

• Usage in hh:mm per session and session start times: Allows for a general idea of how often the program is used in a week and how long
• All searches done and times spent on each shabad (Log the enter time and exit time). This should help with figuring out failed searches which will help with fuzzy search in the future
• Save the id of shabads used in above point so that we can also have an idea of "popular shabads" used throughout the year.
• Settings so we know what are popular options and can decide on defaults in the future for new users. Would also be nice to AB test some options which is a little bit separate but related to this issue.
• A general way to get an idea of where in the world it is popular to use (Timezone + Country is one good option which is still too open to pin-point anyone specifically).

One thing to keep in mind now is GDPR...

More things that would be nice to log:

• Min, Max, and Average search query return time (how long for each keypress to show search results, not returned from db, but actually drawn on screen)
• Num crashes / errors
• Banis used count
