About distributions patches to consider inclusion for a future 2.8.7 release

As talked today on IRC with jean and uwog, we thought would be better to
post here the patches from different distributions that could get
upstreamed if possible.

They are:
- gcc-4.6 compilation issues: It has been reported to:
http://bugzilla.abisource.com/show_bug.cgi?id=13066

Attached patch fixes the problem

- autosave.diff is a patch from debian to enable autosave by default ->
per personal experience, I also agree with enabling this as a good and
safer default :)

- ctrl-comma-subscript.diff -> debian patch to make ctrl-comma (C-,) a
shortcut for subscript text.

- fully-link-plugins.diff -> debian patch to ensure plugins are linked
properly as explained in patch comments

- link-plugins-with-cxx.diff -> another debian patch for linking plugins
better

- mime-types-desktop.diff -> add more handled mimetypes

- mime-types.diff -> support mimes added by preceding patch

- libwpd-0.9.diff -> this one is important to let abiword use latest
(and only upstream maintained version) libwpd version.

- abiword-libpng15.patch -> openbsd patch to fix compilation against
libpng-1.5

- abiword-libpng15-2.patch -> another openbsd patch to fix compilation
against libnpng15

Thanks for taking care
