Bug#959875: RFS: redmine-plugin-apijs/6.4.0-5 [ITP] -- Redmine plugin to display gallery from attachments

[Fabrice Creuzot]

I uploaded a new package release (6.4.0-5).
I fixed lintian errors and I updated debian directory in source repository.

There is one lintian error (at line 13), I will fix for the next release
(6.5).
