[A-368] SBo-git 20100424

- fixed avidemux: substituted slackbuild with alien bob’s one and changed it a little (mainly for using it with sbopkg).
- fixed gtkmm and cairomm (minor stuff).
- rebuilt all my packages, for slackware64-current (x86_64) and for slackware-current (i686).
- the commit with all the patches and the usual “git branch -v”
