Fix lintian issues in debian packaging branch

[Andrew Starr-Bochicchio]

As discussed on the list, there are a number of lintian issues in debian packaging branch:

I: breathe-icon-theme source: debian-watch-file-is-missing

As there hasn't been a release, that makes sense. Assuming that the
official hosting will be on LP, the watch file should look something
like this:

version=3
https://launchpad.net/breathe-icon-set/+download
http://launchpad.net/breathe-icon-set/.*/breathe-icon-theme-(.+).tar.gz

W: breathe-icon-theme source: debhelper-but-no-misc-depends breathe-icon-theme

 ${misc:Depends} should be added to the Depends field.

W: breathe-icon-theme source: out-of-date-standards-version 3.8.0
(current is 3.8.1)

Standards-Version should be bumped to 3.8.1

I: breathe-icon-theme source: xs-vcs-header-in-debian-control xs-vcs-bzr

Vcs-Bzr is now an accepted field. the XS can be dropped.

I: breathe-icon-theme source: binary-control-field-duplicates-source
field "section" in package breathe-icon-theme
N:
N: In debian/control, this field for a binary package duplicates the value
N: inherited from the source package paragraph. This doesn't hurt anything,
N: but you may want to take advantage of the inheritance and set the value
N: in only one place. It prevents missing duplicate places that need to be
N: fixed if the value ever changes.
N:
N: Severity: wishlist, Certainty: certain

P: breathe-icon-theme: no-homepage-field

A Homepage: field could be added to debian/control

I: breathe-icon-theme: extended-description-is-probably-too-short

Or at least the automated check thinks so, but I don't think it can
read. ;-) Wouldn't hurt to extend it a bit.

W: breathe-icon-theme: extended-description-line-too-long

Lines in debian/control shouldn't be longer than 80 characters.

I: breathe-icon-theme: copyright-with-old-dh-make-debian-copyright
N:
N: The copyright file contains the incomplete Debian packaging copyright
N: boilerplate from older versions of dh_make. (C) is not considered as a
N: valid way to express the copyright ownership. The word Copyright or the
N: © symbol should be used instead or in addition to (C).
N:
N: Severity: wishlist, Certainty: certain

W: breathe-icon-theme: copyright-refers-to-versionless-license-file
usr/share/common-licenses/GPL

A specific version (ie GPL-2, GPL-2+, or GPL-3) should be used and
linked to, not just genericly GPL.
