[WIP] Modernizing repo and improving ease of use

[cloudRoutine]

My primary goal was to get this repo setup so people can clone it run build.cmd/build.sh and have everything compile and run without any manual configuration.

To do this I switched to using paket and FAKE for the build process and sqlite & sqlprovider for the tests.

I've almost gotten all of the tests passing, but a few are failing with errors I don't really understand.

@jamescheney could you enable appveyor builds for the repo too?

it was a real pain but I've finally got the CI running properly for both travis and appveyor
https://travis-ci.org/fsprojects/FSharp.Linq.ComposableQuery/builds/214518947

you can see the appveyor results for my fork here https://ci.appveyor.com/project/cloudRoutine/fsharp-linq-composablequery

sorry it took so long for me to get back to this

@jamescheney - if you like we can make @cloudRoutine a joint administrator on this project and the CI as well. He's an active and trustworthy contributor to many F# repos

@cloudRoutine - I think I've done this (https://ci.appveyor.com/project/jamescheney/fsharp-linq-composablequery) but don't really know what I'm doing, so...

@dsyme - That sounds great to me; I unfortunately haven't been able to make much progress on this so see no reason to stand in the way of someone else who can.
