Removed extra ">" from oauth-advanced readme, removed extra whitespaces (auto-save in Sublime), added additional info to base64encoder sample, and removed oauth-authcode sample since it is redundant with (and inferior to) oauth-advanced sample. Also added README for async callout and removed unnecessary text from base64encoder sample.
