added <param name="onload" value="true" /> under iOS plugins config->splashscreen due to a bug with cordova and iOS https://issues.apache.org/jira/browse/CB-4374
we'll wait 1 sec before hiding splashscreen, after all the stuffs are done
added shakeUpdate() since we want to refresh the weather when shacking
we call shakeUpdate as soon as possible so we'll watch the accelerometer
removed  shakeUpdate() 'cause it would be better to call it after the wthr.show
Shake to update feature
