eliot/dic/hashtable.h
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)
