- corrected layout of map preview

- added caption to maps containing latitude and longitude information
- prevented that maps occur on second search page
- added location names to did-you-mean
- some refactoring of did-you-mean
- added equal and compareTo test to Coordinates class to make that work in set
- fixed utf-8 support for library files
- fixed a bug in images search icon view caption
