FIX: Account total spent

It now works with the new design but takes a bit to load all of the
elements from the other pages.
FIX: Issue with account total

Had an SSL error from the throbber image and didn't account for URL
parameters.
Fixed continuous scroll

Changed the continuous scroll to kick off when the pagination element is
in the viewport. Also fixed incorrect calls to runInPageContext.
Merge pull request #628 from JakeH/dev-continous-scroll

Fixed continous scroll
UPDATE: Some code cleanup

Removed the search_threshhold variable which is no longer being used.
Fixed some spacing/formatting issues.  Updated runInPageContext function
for tab_items loaded over AJAX.
FIX: Memory leak in continuous scrolling w/ ea

Previously process_early_access() was being called each time new search
results were retrieved either for continuous scrolling or search
suggestions.  This function would then evaluate each item on the page to
see if an Early Access banner was needed.  Scrolling through several
pages would thus cause exponentially more memory to be consumed.  This
corrects this by only processing the individual items as they're added.
FIX: A few bugs

Just a few small things I found when porting the new features over to
Firefox.
Added currency parsing, updated wishlist total
REMOVE: Old CSS
Merge pull request #630 from JakeH/dev-currency-parsing

Added currency parsing, updated wishlist total
FIX: Formatting and whitespace issues
REMOVE: Cart buttons on wishlist

Valve changed how this is done and it's currently not possible without
scraping a store page to find your sessionID.  This may be re-added
later if a solution presents itself.
UPDATE: Localization file
BUILD: 6.8
Merge remote-tracking branch 'upstream/dev' into dev
