/*
Almost all of this code is by Kyle Coburn aka kiko on WakiKani.
It has been reformatted slightly and some minor changes made.
rev 0.1.1: added a few more options
for classic style: enable only fuzzy_time_mode_past, fuzzy_time_mode_near, and optionally twelve_hour_mode
rev 0.1.2:
change to fix server timeouts on higher level vocabulary
change to prevent always reloading data when no current reviews
increased max display time to 7-days
changed data storage format. now stores number and type of current and burning items. (for more display options later)
added a last updated time (works with 'WaniKani Real Times')
added a basic loading and error indicator
added 'wkt_username_' prefix to localStorage keys (for multiple WK account support)
added a reload button
added invalid API key detection. forget bad key. get new on refresh.
