Started switch to using CursorLoaders

Switched ParamsListActivity to Fragments to display the history using a CursorLoader. It does not auto-refresh when new values are added, which is the same as the existing behavior.
Merge branch 'master' into cursor-loader
First stage of switching to ContentProvider

Query, Insert, Delete commands are functioning but not implemented entirely in the app. Query works for the main status, history list, history popup.
Stripped down the RAData class and renamed to RADbHelper.
Moved params table to own class, StatusTable.
Still have to implement inserting values into database and deleting all parameters from database.
Allow for spaces in portal usernames
Finished switching to ContentProvider

Insert and Delete works. History page gets updated as more parameters are logged. Cleaned up the code and removed unecessary functions. Inserts are now handled from within ControllerTask instead of calling a function inside the application and having to set and read all the data from a ContentValues. This means improved memory usage and performance should be improved even if it is slightly.
Removed commented out code
Merge branch 'cursor-loader'
