Changes 0.11.51:
* Removed the -Wstrict-prototypes option since it causes warnings
  in GTK+ headers which are simply too annoying. Hopefully I won't
  regret this... *"Jaws" theme*.
* Cleaned code in various places where warnings had earlier crept
  in hidden by the flood caused by GTK+ and -Wstrict-prototypes.
* Removed printf() from hex-text-loader which I forgot in there. :/
* Regenerated Makefile, hopefully fixing problem with install.
* Added "Video, MOV" type to default config; quietened mplayer.
* Updated Italian translation, from F. Cosoleto.
