Option to use the "local" project's name (no folder prefix)

Projects within  folders are always displayed with the Folder's path as a prefix, which sometimes defeat the purpose of carefully choosing "display names" for projects and make projects lists more difficult to read.

Suggestion: add a new optional parameter in the folder's configuration, allowing to skip the folder's name when displaying embedded projects names. The parameter's value would default to false, allowing full backward compatibility with previous versions of the plugin.

This would easily allow a greater flexibility in the way folders display their projects names, e.g. the same project – Ancestor/Parent/proj – being displayed depending on the parameter settings of folders Ancestor and Parent:

Ancestor >> Parent >> proj
Parent >> proj
Ancestor >> proj
proj
