app: Updated PayPal contribution with fixed amounts

NOTE: The previous PayPal link was a 'donation' type, which failed for users
      (possibly due to my address being in Japan). Now using multiple "Pay
      Now" links with set amounts.
notifier: Revert to using "8badf00d" to identify timeouts

NOTE: Execution timeouts can be either bug type 188 or 109 (and possibly
      others).
NOTE: Previous code mistakenly used 185, which is actually EXC_RESOURCE.
Updated Localization submodule
Updated for release (v1.7.1)
