Added first stage of notifications

Added notification table
Added notification interface for query, delete, insert, update
Added notification list activity to list the notifications
Need to add creation of notifications
Need to add icon for main menu
Need to add custom add icon for add button
Combined fragment activities into one activity

Now have a FragmentListActivity that handles displaying all 3 of the list fragments based on the extra argument passed in the Bundle.
Renamed Params to History
Added in notification error checking

Notifications are now added, updated and deleted from activity.
Notifications are only checked if notifications are enabled in the app and are checked right after the values are inserted to the database.
Improved the StatusProvider delete commands to use the selection arguments.
Fixed up the precision handling for the notifications

Checking and displaying the notifications is based on the precision of the variable. Temperatures only have 1 digit of precision while PH has 2 digits and PWM percentages have no digits. No need to display the extra precision places if they are just zero.
