Fixed some bugs that would cause edited shifts to return nothing, and the edited availability to return nothing.

Moved to new package for server files. Updated UserThread and DataBaseQuery to work with the both Availability and TimeOff classes.

Employees table now captures the email, phone number, isManager, and wage.
Shift table now captures the availability of the shift. Updated parsing so all employee and shift details are separated by commas.

Added a remove all shifts by employee id method to the Schedule class. Now when an employee is removed there shifts are deleted first from the database then they're deleted after.

Made changes to the Schedule class methods to return data that the client needs to update there local copy.
Cleaned up some spacing and variable names for consistency.
Cleaned up all the warnings.

Added functionality to remove the employee shift by using the unique shift id to both the server and client side.

Fixed bugs with that caused in consistencies with message sending between client and server. All employee data should be updated to all clients when employee data is modified in the database. The client should have an updated copy of employee information.

Changed schedule and staff class so that the connection is made from the model and passed to the staff and schedule class.

Refactored Schedule class to support local MySQL database. Now supports connecting to MySQL database.
