Title: Add FileSetBuilder

It allows to define file sets using CE syntax instead of operators, like this:
```fsharp
let fs = [ "*Tests22.dll" ]

Target "Build" {
files {
addMany fs
add "**\bin\**\*Tests.dll"
add "**\bin2\**\*Tests.dll"
add "**\binaries\**\*"
add "**\binaries2\**\*"
exclude "**\bin2\Special*\*"
excludeMany [ "*t2"; "*t3" ]
}
|> MSBuildDebug @".\out1" "Build"
|> Log "AppBuild-Output: "
}
```
