Add application sctructure

I  have created i MVC 4 application (with .Net Framework 4) architecture
becouse our hosting doesn't support the newest version, but this is OK
too.
The sulution contains 4 projects total.
SpaceAidAppWeb - is the web application
SpaceAidAppData - contains Generic Repo and Unit of work pattern and
also the migration settings
SpaceAidAppModels - contain the code first classes for the db
SpaceAidAppWeb.Tests - if we have time to make tests

About the data base
Currently the commited project uses localdb which will be created
autamatically after running the app, we will have to switch it to
another Db at some point
