Olivier Teulière e7a8d01a8d Merged the "cppdic" branch back into HEAD.
There are too many change to list properly, here is an overview of the main changes:
 - the dictionary is now in C++
 - the dictionary has a new format, where it is possible to specify the letters,
   their points, their frequency, ... It is backwards compatible.
 - Eliot now supports non-ASCII characters everywhere
 - i18n of the compdic, listdic, regexpmain binaries
 - i18n of the wxWidgets interface (now in english by default)

* This class centralizes the various configuration options of Eliot.
* It implements the Singleton pattern.
*
* Currently, there are few settings, and their initial value is hard-coded.
* In a later phase, this class will be able to export/import settings
* to/from a configuration file, and it should be possible to override
* configuration settings with settings given on the command-line (TODO).
* The boost::program_options library could be useful for this.
*
* This class will also be helpful for the "Settings" dialog box of the GUI.
