- (BUG) don't limit dictionary lines, file names and words to some static size
- (BUG) fread file using fread. The fget is causing problems with the last
  dictionary line - (?) it's ignored or double readed some times... and
  the output break one line if the last line has EOL else (if has EOF) not.

- call Search_word for each char, not for each line (more flexible)
- continue searching word if had found it on a previus line? (now: yes)
- case sensitive (a!=A)? (now: yes)
- wole/partial words matching (now: wole)
- read compressed dictionary files on the fly (with Zlib)
- dictionary stay running and exchanging data with sockets connections
  (speed up)
- add before and/or after: the outputed line or the word found or the mean
  some special parametrized string (good to do formated output!)
- just output all possible words
- don't output the line (just exit, usefull to know if the word is present)
- output only the exactly word mean or the wole line?
- output test words or only the word tags (<vort/o> or vorto)
- make (optional) index system to speedup word search

Graphic interface:

- (BUG) solve problems with $Interf_files_type_1 and $Interf_files_type_all
  in file chooser dialog
- (SEMI-BUG) better error messages (word not found,... using program exit code)
- show abreviations in another window area, or inside text but
  with other format (italic?)
- words found with other format (bold?)
- dialog to see all dictionary words
- some audio error signal
- combo box to enter the word to search for (make easy search again)
- entry for many words in the same time (foreach...?) (maybe a bash script...)
