Fixed for 0.24.2

Changed the variables to reflect the API changes of 0.24.2.
Now using automatic versioning in VS.
Now using Module Manager's solution to avoid multiple instances (needs
more testing).
Removed the MM code from start

Removed everything from the Start method: turns out, the MM solution
can't work for this.
Clarified a lot of comments.
Added a lastSeen value to the default kerbal file.
Public DB property and examples

Fixed a small logic bug in the file update logic.
Moved all the references to their own folder inside the solution.

Interface:
Changed the name of the flag from available to installed.
Exposed a get-only access to the server's DB.

Created an examples project with an example generator and an example
client. The client is not working right now: is it a bug in the client
or in the server?
Fixed Instance bug

Fixed the Instance not getting assigned during start.
