Rename files in tutorials?

I have always been wondering why our tutorials are called plot_*, even though many tutorials do not produce a single plot. @hoechenberger pointed me to the reason, which is that this is just the default Sphinx naming scheme. However, we could change that (https://sphinx-gallery.github.io/stable/configuration.html#build-pattern). In fact, we only have plot_*.py files in our gallery folders, so we could easily create a rule that build all *.py files. WDYT?

note that we have some examples that do not contain plot_ (I think about the RSA decoding example).

These should be taken care of by my suggested _sgskip process above

Also I foresee that google will need to reindex everything. So we’ll have a lot of broken links. You can find many of my slides online and you will break on the URL they contain

It just occurred to me that I could write ~30 lines in conf.py to handle this by writing out plot_* HTML redirects for all of our examples. I think this should make Google and your slides happy, and also make it so that in the future if we want to change page locations we can trivially (in one line) add arbitrary redirects from old-to-new names.

The reason is long execution time. They are rendered by Sphinx from rst to html without running the py code or capturing output.
