a lot!!! of changes

added main menu
added debug display
many debug widgets for plotting live data
worked on android live sensors
added offline-data sensor feeding
some dummy data sensors
worked on the map display
added ui debug for grid-points, particles and weights
added a cool dude to display the estimation
added real filtering based on the Indoor components
c++11 fixes for android compilation
online and offline filtering support
new resampling technique for testing
map loading via dialog
