Add an activity that allows the home owner to search for a service provider.

[ghost]

This activity should allow for searching by:

• Type of service
  • Just an edit text that allows for searching services by name should do.
• Availability
  • This should show the day of the week to search availabilities for and the time slot that the home owner is available to be serviced.
  • The days of the week should be selectable as a drop down view.
  • The exact time should be represented as an availability object using a simple text view and editing this should be done using the AvailableTimeSlotEditorActivity.
• Rating
  • Simply set the rating using a RatingBar.

The actual searching functionality will be done by the SearchUtil class. This is only for the user interface.
