- few bugs fixed
- added suport to Ole Extent measurments to improve compatibilty

* modules/gui/wxwindows/wxwindows.cpp: don't use the saved positions/sizes when acting as a dialog provider.

autoplayed

item-ext.c: reverted a recent change in GetPositionById than caused
old-style playlist to malfunction (visible in rc interface at least)

Make compilation of mozilla plugin easier on different distributions. Removed fixed include paths from mozilla/Makefile.am. XPIDL_INCL is automatically determined from ${MOZILLA_CONFIG}. 
Configure and compile with XPIDL=<path_to_xpidl> application of your mozilla version, eg for mozilla-1.7.6 use: XPIDL=/usr/lib/mozilla-1.7.6/xpidl ./configure <rest of line> && make

* src/misc/modules.c: added sub-version number to cache data (used to detect cache layout changes in the development version).

* modules/gui/wxwindows: bunch of small improvements to the embedded mode + enabled saving size with --wxwin-autosize.

- fix silences handling

   module "mosaic-bridge".

* modules/gui/wxwindows: disable last commit for now since we don't seem to be able to retrieve the right size values.

(Trivial patch)

* src/misc/configuration.c, ALL: support for auto-saveable config options (saved automatically on exit).
