CompilationDatabase: Ask for the root path and scan for headers

Let's use the same approach we have for CMake projects by using
the same TreeScanner class.

Compilation database does not have a concept of the root directory
so let's show a file dialog and ask for it the first time the project
is loaded. Next times we open it we take this path from settings.
This root path can later be changed from the project tree context menu.
