[Toaster] [PATCH 3/6] eventreplay: fix event loading code

[Ed Bartosh]

Event objects are represented by base64-encoded strings in
the event file and can't be loaded by existing eventreplay code.

Fixed the code of loading events from file by decoding base64 strings
into the binary form and loading them with pickle.load.
