added settings functionality. reads the settings and performs actions. now i need to add a onsharedpreferenceschangedlistener and make this proper.

also added a countersettings class to make storing the settings of individual counters simpler.

whew this is tough but cool
moved sharedpreferences to settingsClass object first to avoid repeat sys calls

had created a onsharedprefs listener in the counterfragment but it can't communicate effectively with the prefs fragment so i'll have to move it to the prefs fragment and communicate through the activity or move the prefs fragment to it's own activity. i dunno. have to redesign the whole thing in photoshop :(

my baby, i hope u turn out alright in the end
