Fix #144.

Provide a somehow acceptable manual page for GlobaLeaks.
Sad to say, but with this commit we have another place hosting documentation,
and that's a shame (going to open another issue for this).
Copyright in sphinx documentation mentioning a copyleft license.

Hoping that @vecna will love this quote from Principia Discordia.

Partially fix #1027.

Move documentation directory top-level, and change scripts accordingly.
Remove fucking test enumeration from globaleaks.tests.handlers.test_rtip.
Skip test_templating.notifTemplateTest.test_keywords_conversion.

This is to avoid true negatives in travis builds, working around bug #1024.
implemented wb login box, cleaned theme
Merge branch 'devel' of github.com:globaleaks/GlobaLeaks into devel
give me your mastercad whistleblower!
Remove fucking test enumeration in globaleaks.tests.handlers.test_collection.
Update .gitignores around.

Hide useless files in appliance/ and doc/ directories.
Accomplish fix #1027: move backend/debian into debian/.

Move debian directory top-level, plus ignore all irrelevant files from source,
and update appliance scripts accordingly.
XXX. globaleaks.deb shall be in common for all these appliances scripts, in a
separate file under appliance/.
Update .gitignore with respect to latest commit.
Introduce packer user variable `deb`.

The introduction of this variable is due to the fact that packer does not report
in the official documentation any way to guess globaleaks version, and find a
globaleaks debian package automagically. Therefore, from now on the user will
have to specify this variable pointing to the globaleaks .deb file generated by
dpkg. E.g.:

$ packer build -var deb=../../../globaleaks_2.60.30_all.deb template.json
Add python to Depends in debian/control.

Apparently it must be explicitly reported, otherwise lintian complains with:
E: globaleaks: python-script-but-no-python-dep usr/bin/gl-admin
E: globaleaks: python-script-but-no-python-dep usr/bin/globaleaks

(thought that python-dev was just fine as well).
Ignore appliances output-* directories in dpkg-source.

This way, you can build a sane debian package while building a vagrant machine.
Add draft for template in debian jessie.

It's already working!
Remove debian/ directory.

This commit prepares the repository to host new subtrees containing different
debian directories.
