V2 add image update

[mxritzdev]

The Update Feature is doing:

• Updating Information (Name, Author, Startupcmd, ...)
• Updating Variables and docker images (removing unused, updating existent, saving new)

[Masu-Baumgartner]

And use FirstOrDefault instead of Any + FindIndex. This reduces the db calls. If the item is missing the return value would be null

[mxritzdev]

The FindIndex and Any are called on a local list instead of the db

[mxritzdev]

So it would not really make a difference

[Masu-Baumgartner]

Another thing is that all server using the image need to have their variables updated too as they would stop working if the image varaibles get updated

[mxritzdev]

Oh, i didnt thought about that, i will do that later/tomorrow
