Add lauchpad support to LibreOffice testdoc collector script

[Björn Michaelsen]

In the core LibreOffice repository there is a Python script
bin/get-bugzilla-attachments-by-mimetype

This can download all sorts of interesting bug attachments
("bugdocs") for testing purposes from various bug trackers,
currently including bugs.freedesktop.org, openoffice.org bugzilla
and bugzilla.redhat.com.

There are more bug trackers that contain interesting attachments,
and support for these should be added:

- ...
- Launchpad
- ...

This requires no LO code or C++ knowledge whatsoever.

and support for these should be added:

- Novell bugzilla
- Launchpad
- whatever is used by KOffice/Calligra
- whatever is used by AbiWord/Gnumeric
- anything else likely to contain ODF or other office format bugdocs

This requires no LO code or C++ knowledge whatsoever.

For launchpad, this:
 https://help.launchpad.net/API/launchpadlib
is the way to go.

Launchpad has an API that will let you do this. No changes should be needed to LP, but if there are please open a bug about those changes.

[Gökçen Eraslan (gkcn)]

Robert, can you review this[1] request about this task? Since we iterate over all the bugs having the attachments those are matching our mimetype criteria, I think searchTasks method needs some improvements.
