Introduce optional 'name' field for iconpack icons

This introduces a new (optional) 'name' field for iconpack icons. It
will be used to describe the icon in the icon selection dialog. If it is
not present, the name of the icon will be derived from the filename,
like before. Using this new field allows usage of more exotic characters
in the icon name that are not allowed in a filename.
