PimNote change log

• Bug fix on cached files. Opening the application with a remote file loaded from the cache folder causes it's tab to freeze for a while when this tab is selected and the network is disconnected.
  

• Add checking on file modification time when saved to prevent any files loaded from the cache folder in %appdata%\PimNote\unsaved to silently overwrite the real file that was changed from other device.
• Add deleting "new*" file in the cache folder when saved using Save As.
• Bug fixes on content replacement. Content replacement after external file change sometimes doesn't occur automatically because the file reading starts too early and the conflict may empty the file. The content replacement also doesn't occur in the tab that is not currently displayed. The content replacement doesn't occur when the file is loaded from the cache folder. The content replacement doesn't occur when the file is emptied.
• Bug fix on recent file list. Pressing Ctrl+R doesn't change the caret to the recent box.
