Refactor json parsing using loop + associative array

[Costinteo]

The json parsing seen below is not the most adequate in regards to good practices:

ipfetch/ipfetch

Lines 17 to 26 in 1e2bf53

	ip=`sed -nr 's/.+"ip":"([0-9\.]+).+/\1/p' "$tempfile"`
	continent=`sed -nr 's/.+"continent_code":"([^"]*).+/\1/p' "$tempfile"`
	city=`sed -nr 's/.+"city":"([^"]*).+/\1/p' "$tempfile"`
	isp=`sed -nr 's/.+"organization":"([^"]*).+/\1/p' "$tempfile"`
	country=`sed -nr 's/.+"country":"([^"]*).+/\1/p' "$tempfile"`
	timezone=`sed -nr 's/.+"timezone":"([^"]*).+/\1/p' "$tempfile"`
	latitude=`sed -nr 's/.+"latitude":([^,]*).+/\1/p' "$tempfile"`
	longitude=`sed -nr 's/.+"longitude":([^,]*).+/\1/p' "$tempfile"`
	asn=`sed -nr 's/.+"asn":([^,]*).+/\1/p' "$tempfile"`
	region=`sed -nr 's/.+"region":"([^"]*).+/\1/p' "$tempfile"`

It should probably be refactored using associative arrays (dictionaries) and a loop. There are some minor tricks to this - the regex pattern isn't always the same - but it could be done without much hassle. I propose this to anyone who wants to contribute. :)

@trakBan, would be great if you could label this with "Suggestion" or something like that. + "Help wanted" or "Good first issue".

Yes i agree, im going to look into doing that myself.
