revert to use msbuild libraries that come with the core framework, which requires eliminating .net 4.51 checking when building proto compiler.
when building the protocompiler, Seq.list is not available so instead use copied implementation for generalized slicing parser only when building proto compiler.

    Implements extended if grammar

    Origin: https://fslang.uservoice.com/forums/245727-f-language/suggestions/6079342-allow-extended-if-grammar

    This commit adds the possibility to write condtional compilation expressions like this:
     #if SILVERLIGHT || NETFX
     #endif

    or a bit more advanced:
     #if (SILVERLIGHT || NETFX) && COMPILED || !DEBUG
     #endif

    This commit doesn't add #elif which is an orthogonal problem.

fixes #27
resolves #28
