/*
 as key presses happen, detect if there is currently a url being typed
 if a space or blur happens after there is a current url, scan text for urls
 for each url found, check to see if we have it, if not, add it to the list
 as key presses happen, detect if existing text is being modified (delete or backspace) and reverse check urls to see
 if they should be removed
 This doesn't handle when text is highlighted and something other then delete or backspace is entered
 so instead, maybe we can just see if the text length has decreased and then re-reverse check urls
 Note: but this isn't necessary since we are removing the URL as we go... so wtf?
