Solution file parser should parse and preserve ProjectSection(SolutionItems)

[KirillOsenkov]

Currently the solution parser just skips over solution items, here's the code:
http://source.dot.net/#Microsoft.Build/Construction/Solution/SolutionFile.cs,775

Since the solution parser is the only public and official .sln parser it'd be nice if it supported parsing solution items, which is easy to add. Here's an example syntax:

Project("{2150E333-8FDC-42A3-9474-1A3956D46DE8}") = "Solution Items", "Solution Items", "{E3D2D556-C8D6-4107-902F-5092299605DC}"
	ProjectSection(SolutionItems) = preProject
		nuget.config = nuget.config
		tools.proj = tools.proj
	EndProjectSection
EndProject

. . . kind of. It was never intended as a general-purpose thing, only to meet MSBuild's needs. I'd love to see solution understanding in a separate library that we could use--if that was done, this would be an obvious feature request there. For MSBuild's internal needs, I'd say no way. But people definitely do (ab)use MSBuild for this purpose.

Parsing all the random solution files out there (including all the quirks of VS going back 20 years + all the quirks of randomly tool generated and hand edited solutions) is not as simple as it seems. This code has stabilized to cope with that more or less so there's certainly value in allowing this to be used in a reusable way.

Any chance to get SolutionFolder files parsed soon?
