Added OmniSharpFindType command.

This new command behaves exactly like OmniSharpFindSymbol, but only
for types. The main motivation was improved performance. The
SymbolFilter parameter in the /findsymbols endpoint got added with
the merge of pull request #1823. A version of omnisharp-roslyn with
this PR included needs to be installed.
