Added first cut of Femah.Examples solution with Femah.Examples.WebApp

#12 Remove Femah.TestEebApp out in to a separate repo/solution/NuGet
package
- Added first cut of Femah.Examples solution with Femah.Examples.WebApp,
currently this will not build as all Femah dependencies are missing.
- Do we both with a build script for this or rely on VS for the time
being until we've at least hit MVP?
#34 Add Web.Additionator to Femah.Examples Github repo

This got a little involved, trust NuGet to get in the way, the
highlights:
- A new Femah.Examples solution structure, introducing the \Web solution
folder
- Removed existing test web app
- Ported Additionator (core, core.tests and web projects) across (need
to sort out some namespace overhang from it being someapplication as we
go along)
- Introduced Femah.Core as a NuGet package reference
- Everything is .NET 4.5, we need to attack this once Femah.Core is
bumped down to a lower framework dependency.
- Really put the cat amongst the pigeons and have untracked all packages
from the solution level \packages folder and added an exclusion to
.gitignore

Correcting the above to actually do it!
