Replace "matplotlibrc" by "rcParams" in the docs where applicable.

anntzer · anntzer · commit aa71657da63f · 2018-03-27T18:13:36.000-07:00
In preparation for the possible switch to the new rcsystem. This doesn't touch any place actually documenting the rcsystem, just places where "the foo param in the matplotlibrc" can reasonably be replaced by "the foo rcParam". The `examples.download` and `examples.directory` rcParams removed from doc/matplotlibrc have been removed in 6c5e961 (2012). The verbose.level rcParam is deprecated, update the docs accordingly.
