Gryptonite (formerly GPassword Manager) Files

This is what I hope will be the last release in the 3.0 line, as it seems the code is fairly stable so I don't want to mess with it too much. This release only contains a few changes over the previous one, but some of them are critical.

Here's what changed: * Fixed a rare but critical bug that affects the following scenario: If you deleted an entry who had children which are favorites (or grandchildren, etc...) then the cache was not updating properly and could cause a crash. The really bad thing is there was also another bug that when you tried to load your file after such a crash it would never open but repeatedly crash. I fixed both these bugs in this release, and I hope nobody actually ran into this! * When the application locks the undo/redo text is cleared (this fixes a security flaw) * The search control only uses date filters instead of date-time filters, and it has a nicer calendar selection widget * When you pop out entries that only contain URL's, the window doesn't show anymore * The tray icon tooltip changes when closing a file, to indicate that it's busy
