Fixed typo Recognised to Recognized for PR#542.

[vloschiavo]

Replaced "Recognised" with "Recognized"

./Damselfly.Core/Services/StatisticsService.cs:            ObjectsRecognised = await db.ImageObjects.CountAsync(),
./Damselfly.Core.DbModels/Models/API Models/Statistics.cs:    public int ObjectsRecognised { get; set; }
./Damselfly.Web.Client/Shared/Stats.razor:                <td>Recognised Objects:</td><td>@statistics.ObjectsRecognised</td>

./Damselfly.Core/Services/StatisticsService.cs:            ObjectsRecognized = await db.ImageObjects.CountAsync(),
./Damselfly.Core.DbModels/Models/API Models/Statistics.cs:    public int ObjectsRecognized { get; set; }
./Damselfly.Web.Client/Shared/Stats.razor:                <td>Recognized Objects:</td><td>@statistics.ObjectsRecognized</td>
