minor updates

Hey Dov,
thanks for your plugin. love it. 
While working through it i found some stuff that probably relates to older releases and causes xcode issues. 
I changed some things concerning getMonitoredRegionIds, getPendingRegionUpdates, accuracy variable and read me.

One issue remains "regionMonitoringEnabled" is deprecated in iOS 6, which i haven't fixed yet.

let me know what you think.
