Even if the CGI fails for an unknown reason we still have the content type, which should
satisty the web server

I thought mkstemp would do that by itself. While it may seem not very satistfactory to hardcode
the path, /tmp is POSIX.

pdf.js : debug default clone list for pdf > with multi-system the first 5 clone in the list can be unactive

See 183ad875.

This code was duplicated in 60a8bf4a.

This test was already working, but threw an exception, and the test coverage could be ignored.

germline_builder : continue to build germline even if the system is not referenced in germlines.data (or if the browser can't access to germlines.data)

Simplification of the code.

Closes bug tested by 14b16e9c.

Bug: With a reasonnably large -r option (such as 2000), no representative is found.
This is because min_cover is larger than max_auditioned.

If -w is below the seed weight (hence the junction size), strange things may happen,
as for example a clone without representative.

Closes bug created by 59a1bcf6.

59a1bcf6 added some spurious output that breaks CGI.
Thanks to @mikael-s for pointing that out.

fastaToJson.py : repair/update > python script, used to produce germline.js with fasta file from germline folder

Kmer is used inside a IKmerStore<Kmer>, its constructor should thus accept
the (label, stand) parameters.

We had too few gcc warnings.
