inspection fix (rubberduck-vba#1696)

* added AsTypeName to the context-sensitive commandbar

* clear built-in references at every resolution; fixed issue with null parse trees, given built-in modules get a module state instance.

* fixed OverflowException in GetTypeName; built-in parameters now have return type info :)

* returning built-in members now have return type info as well

* removed hard-coded defaults in ClassModuleDeclaration

* added IsBadReadPtr check in COM declarations collector

* Implemented CanExecute in Project Explorer rename command

* cleaned up FormDesignerRefactorRename command

* fixed IOExceptions in QualifiedModuleName

* use filename, not buildfilename

* GetDisplayName being the part in parens, should be null when not applicable; made it private

* renamed namespace Rubberduck.UI.CodeInspections to Rubberduck.UI.Inspections for consistency with Rubberduck.Inspections namespace

* changed background color of bottom panel in CodeExplorer and InspectionResults toolwindows

* fixed broken keybinding "Esc" -> "Escape"

* added copy/export button to SearchView (todo: implement ExecuteCopyResultsCommand)

* Revert "added copy/export button to SearchView (todo: implement ExecuteCopyResultsCommand)"

This reverts commit e9946b7.

* assert ProjectId isn't null

* fixes rubberduck-vba#1664

* some French translations

* fixed possible NRE's in QualifiedModuleName

* fixes rubberduck-vba#1671

* changed wording of fr resources for settings dialog (left pane items)

* fixes rubberduck-vba#1672

* more French translations

* fix RuntimeBinderException with optional object parameters (resolver bug)

* fixed AsTypeName of optional parameters with a default value

* fixed "resolving" state in the status bar

* fixed FunctionReturnValueNotUsed firing on Sub procedures
