[UVFe] Please sync exuberant-ctags from unstable

Binary package hint: exuberant-ctags

Please sync exuberant-ctags 5.7 from Debian unstable.

Upstream states: "This is a substantial release. It contains a lot of bug fixes. This is the first release since Exuberant Ctags has moved to multiple maintainers."

This fixes at least bug 129420 and quite some more, which had not been reported in launchpad.

ctags is an important tool for development and therefor we should provide the best available version of it.
