Fix the send: rule of Makefile, to always send all the .html/.pdf even if they are git-ignored

[Naereen]

When I wrote this new version of CP, I was happy to add --csv-exclude and --exclude=.git and --exclude-from=.gitignore options...

But as a results, the .html and .pdf versions of the notebooks are no longer automatically sent to this folder on my website...
I don't know how to have both a git-safe send rule and an inclusive send rule to send HTML/PDF files.

If I write something like:

send:
        CP ./*.html ./**/*.html ${Szam}publis/notebooks/

then it works for 0-depth files, but for files in sub-directories, they end up on the root directory of the target...
