build issueslist from cache before hitting the web

[thatpixguy]

since it might take time even when the web is up we should probably serve up the cached version immediately

[thatpixguy]

which would mean two load notifications, rather than just one. in the tutorial, they remove themselves from the notification after receiving it once... is this best practice?

... only if you want to avoid a pesky crash: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Notifications/Articles/Registering.html#//apple_ref/doc/uid/20000723-98846

good idea but will require some much needed surgery on getIssuesList. could loading the cache be considered fast enough to do at object creation without the need for callbacks? probably not since it does IO...
