All data from netrunnercards.info are now fetched with one query. Also changed preview to be shown with mouse enter

I added new function that will populate foreignCardData variable with all cards using only one query

Therefore user needs only send one query instead of many queries when clicking cards. This will improve performance and user experience (no more waiting for data)

Please ignore typo in utf-8 commit :)
It should be "is now utf8"
