Changed mEvent for mSpeakerIds

/src/org/osuosl/ocw/Schedule.java: Seeing as the only variables being used of mEvent was speaker_ids I've changed from mEvent to mSpeakerIds as a global variable. Also reflected when saving the app state. Added null and empty check for server response in jsonModified
Forgot to add getter for speakerIds in StateChangeData
Rolled back to using mEvent but expanded its usage to reduce Event object creation
Fixed bug loading tracks and events

/src/org/osuosl/ocw/Schedule.java: For loop for retrieving all tracks and events had to start at row 1 and end at number of rows.
Changed timeout in schedule json to higher value
mCurrentDate should never be null so checks removed

/src/org/osuosl/ocw/Schedule.java
Removed unused code, moved showList from setDay

/src/org/osuosl/ocw/Schedule.java: removed some unused code. Added some comments. Removed call to showList from end of setDays and added to the methods that called setDays and needed showList to be called.

Moved loadSchedule method inside asynctask

/src/org/osuosl/ocw/Schedule.java: The necessary logic used in loadSchedule is now inside the load and refresh asynctasks. Added a null and isEmpty check on DAYS in onCreate as when switching days using the day list would create a new DAYS object.
