- Do not use "Done" button style to demonstrate that and advanced search is active. This might seem like an easy solution, but it does not work well in iOS 7.
- Removed implementation of EMSConferenceChangedDelegate. The EMSSettingsViewController and EMSMainViewController uses the core data model as a synchronization point. Also, we are using unwind segue to dismiss the EMSSetttingsViewController.
Several navigation/ui changes:
- Moved search/filter and settings buttons to bottom toolbar since the top navigation bar was a bit to crowded.
- Use text titles in main list segment control. This is in my opinion clearer than icons, and also looks better across different iOS versions and different device orientations.
- Use text titles for «Apply» and «Clear» actions in the  search/filter dialog. This is a bit clearer and also in accordance with Apple HIG.
- For the iPad the search/filter and settings dialogs are displayed in a form sheet style dialog instead of a full screen modal window. .
- Use Plain style buttons across the board in toolbars as it looks better when using icons in the button. Also this is the new standard in iOS 7.
- Upgraded the storyboard for iOS 7. Also fixed some layout issues in iOS 7.
