caja, caja-dropbox, caja-extensions, engrampa, marco: fix stuff, add lintian-overrides

I don't want to change your package definitions. ;-)
I just want to fix some stuff that is easy to fix.

lintian-overrides - should be self-explanatory, are used the same way in Debian testing

caja-dropbox/debian/rules - fix the lines so that it really deletes the static libs

changelogs - editing a changelog is not elegant, but remember that those were errors according to the Debian guidelines. A name entry must always be `Name Last-Name <nick@domain.xx>`. And Debian revision shouldn't be 0.
