Set up konqueror interface to TDEIO:HiddenFileMatcher object:

  (1) Establish "HiddenFileSpec" key to be stored in a konq*viewrc config file.
  (2) Establish menu access for modifying key in listview (iconview TBD).

The "HiddenFileSpec" key (under [Settings] in config/konqlistviewrc) should contain
a string specifying what constitutes a hidden file. The string should conform to
the syntax described in latest commit message for corresponding tdelibs PR # 163.

Testing at this point will require manually editing the configuration file.

KonqListView::slotChangeHiddenFileMatcher will eventually call a dialog through
which a user can query and modify the specification for how "hidden" files are to
be identified. Currently it only demonstrates access to HiddenFileMatcher methods.
