Added GPS information and 

Main Changes 
-------------------
- introduced GPS information
- introduced some of the missing connections between the preferences and the actual code
- modified the way data is uploaded to the server:
     1. long/lat and time are not associated to every single reading. This is a waste of data upload. Data is compacted into a list containing all the variables and which is uploaded in one go with a common  time/lat/long.
     2. taken care of cases where the server is not responding: created a local database where data is temporarily stored. Data will be sent next time the app is loaded
- the interface does not have a table with all data but a textview with only the current data: this is much easier to read
- the font color has been changed to greyish to white (I could not read it)
- the names of the views in the interface have now a positional name (row1_column2). This is because in the future it would be great to have the allocation of data flexible (so that you can change what is displayed where
- other minor changes

Issues
--------
The data displayed is wrong. This is not an issue with this branch. It is something that happens also in the original repository.
apologies that was a change I did for a test and I left it by mistake]Of course I do not wnt anyone to upload their data to my server!
