Fix #131 Workspaces directories in server are not being found

[genericptr]

@mvancanneyt It was broken since your refactor but I fixed the usage of the includeWorkspaceFoldersAsUnitPaths which was supposed to add unit paths to FPCOptions. This for projects without lazarus so that you can open a workspace and it can find files for you with adding them manually.

My question is, how does this interact with the lazconfig system? I'm looking in PasLS.LazConfig.pas and I don't see how it sets unit paths. Now that this is working I think it's going to conflict with the lazconfig.

[mvancanneyt]

It won't conflict. The two systems are completely parallel. it just means many paths will be supplied twice.

Looking at the diff, it seems to me you simply didn't set the
``ServerSettings.includeWorkspaceFoldersAsUnitPathsorServerSettings.includeWorkspaceFoldersAsIncludePaths`
to true.

But I'd need to investigate more deeply. The diffs are not very clear, mixing formatting and functional changes...

In each case, The lazconfig system needs an update. Today you can simply use '/path/to/workspace/**' and the lazarus codetools will automatically add all subdirectories. So no special code required.

Sorry for the messy diff, I'm trying to fix formatting as I go along. It was totally broken because it wasn't actually setting the compiler flags but that fixes this now. I'm going to merge this but if you need to update the laz config or this causes problems then please post a PR. Thanks Michael.
