* Upgraded ASP.NET MVC to 5.1.0 from v4
* We were using a beta version of Entity Framework. EF6 has been released for a while
* MySQL Connector now supports EF6, no need for my custom build anymore
* Updated other libraries to their latest  versions
* Updated mono to 3.2.6

Not tested
git clone takes very very long time and large disk space.
I've sent pull request to use tarball and it has merged.
