Added a filter in OdometerView

[SanjaySiddharth]

What it Does

• Closes IMPROVE - Filter OdometerView by Vehicle #350
• Added a filter in OdometerView which shows the readings of either all the vehicles(default) or any one selected vehicle
• Fixed typo in a commented line
• Added 3rd car and another reading to the preview in OdometerView

How I Tested

• Run the application
• Add three vehicles from the Settings tab
• Navigate to Odometer screen and create some readings for each vehicle
• Click on the filter button in the toolbar (prior to the plus sign(+))
• Choose the vehicle you want to filter on . By default it shows all the vehicles.
• Repeat the above step, but select All Vehicles to ensure all readings reappear.
