Display files in proj order for F# projects, matches VS

[farlee2121]

Motivation

Improve the F# experience by matching fsproj file ordering with Visual Studio, since F# file order matters for compilation and dependency.

Current Behavior

The solution view sorts files alphabetically for all project types

Behavior after PR

F# files are not sorted in the solution view. They remain in the order they were discovered using the fsproj file. This matches Visual Studio. I also verified behavior for project items that match multiple files.

I think we could probably close #131. F# files are properly added, renamed, and removed from fsproj files. Not as part of this PR, but it must have become supported by some previous work.

Follow up work

It'd be good to either

• Add move up and move down commands for F# projects
• OR make it a bit quicker to access the proj file where we can edit the file order

It's also a bit unintuitive that new fs files add to the last item group and not to the item group containing other Compile project items. Perhaps we could modify XmlManager.checkCurrentItemGroup to prefer a group containing the same kinds of items before defaulting to the last item group?

I opened another PR for an optional switch to opening project files on click
