Add x86 platform but there's trouble with Win32
Fool around with platform to try fixing win32/x86
Pack Win32 as -pre1b
.nuspec needs to know where to find x86 files
x64 Core.dll is in a x64 folder

Another kind of errors clean builds will ruthlessly reveal :smile:
Add CI version config
Will it pick up appveyor version?
Make CI NuGets unique by %APPVEYOR_BUILD_NUMBER%
Let -preCIxxxx get ahead of -pre1b in the queue

I think it will work with the following scheme:

* Official releases have no `-pre`
* Prereleases get `-pre{number}
* CI aka nightly builds get `-pre{number}CI{nnn}` where {number} is the previous pre number

Let's try it and see if I guessed right with NuGets "which is the newest" algorithm
Update CefSharp.Common.nuspec to reference CefSharp.Core rather than copy to local dir in pack.bat
Merge branch 'platform-av-pain' of https://github.com/jornh/CefSharp
Publish to myget - testing purposes
