Add subtitle
add a test metadata for #98
Add documentation about the RELATIVE_URLS setting. Thanks to Günter Kolousek.
Removed a bug (debug messages was not showed) and improved readability
Pelican is an "it", not a "he"
removed unused import
include the default values of the settings in the 1st column in parens

this way, it is much easier for the reader to see which variable has which
default value. I also added some default values which could not be found in
the documentation before.
fixed the writings of two variable names in the settings table
various grammar fixes
removed a useless comma
removed a confusing question mark
move a default value to the table cell it belongs to
added missing whitespace in the CLI help
another whitespace mistake in the CLI help
typos, grammar mistakes, minor whitespace issues
Thanks Simon Liedtke
Little doc fix
theme switch
update the theme (logo)
add a KISS plugin system
