local storage to make the calorie count persist. make count persist incase of tab closure

[gnaaruag]

Hey Andrej, love how uncomplicated and practical this is. if you are open to it, i would like to suggest making it so the calorie data is persistant with the help of browser local storage. so that whatever calories we do add or subtract persist in case of closure of the tab. if its ok i would love to make a pr for this.

I'm possibly open to it, I didn't do this because I was worried local storage is exotic enough feature that it opens doors to 100 issues of the type "on my computer X browser Y it doesn't work why". I just don't close the tab :D. But I'm not familiar with the current state of local storage support among platforms and browsers.

local storage is very practical for this sort of application, and is supported by every commericial browser, your point does make sense, it would be better to just keep the tab open, but at the same time we could implement browser local storage as a safety mechanism, so in case you accidentally close the tab you dont loose the day's progress.

Maybe if it can be done in a very defensive, highly optional way, so it works just fine without it, in the current way.

could add a checkbox to opt in or out of data persistence to my pr or can drop the whole thing, your call really! but as far as i can tell my current pr shouldnt cause any issue
