Remove the "seeking too far" error, as it happens for broken AVI and is quite confusing

- ActiveX: support for libvlc and common scripting APIS, widl has replaced midl as default IDL compiler

Will have to be updated/factorized when new chain and filter stuff is in.

Object::connect: Parentheses expected, signal QTimer::timeout

* Add a CONNECT macro for simple signal->slot connections 
* Untested save support in simple preferences

(untested)

* Remove i18n_string stuff

Provide trivial work-around for users of obsolete autoconf

- configure.ac: autoconf 2.59c is not yet supported in Cygwin, added Wine support for ActiveX plugin

    (fixed more coding style, and resolved a conflict I introduced)

(you don't expect me to actual try to compile VLC on puma.cti.ecp.fr, do you?)

* Contribs: change gz => bz2 for autoconf package

    in the configure script.
