nginx_alias_map: A Plugin for Pelican

This Pelican plugin creates an nginx-compatible map between the final page locations
and prior locations, defined in the "Alias" attribute for any article or page.
Loosely based on pelican-alias by Chris Williams,
which itself was inspired by jekyll_alias_generator.
Installation
This plugin can be installed via:
python -m pip install pelican-nginx-alias-map

Usage
Add the directory to the base plugins directory to PLUGIN_PATHS in
pelicanconf.py, and then add nginx_alias_map to the PLUGINS list. For example,
PLUGIN_PATHS = ["plugins"]
PLUGINS = ['nginx_alias_map']

Definable parameters (with defaults in brackets) allow some configuration of the output
of the plugin.
There are two definable parameters, one from Chris's code (ALIAS_DELIMITER), which
defines the delimiter for multiple aliases for the same item; and ALIAS_FILE, which
defines the final name of the output file containing the map; and
ALIAS_DELIMITER : Delimeter between multiple aliases for the same item [","]
ALIAS_FILE : Name of map file to be placed in `output` ['alias_map.txt']
ALIAS_MAP : Name of the map used in the alias file ['redirect_uri']
ALIAS_MAP_TEMP: Name of the map used in the alias file when 2-stage lookup is needed ['redirect_uri_1']

Support for URLs with query strings
In the event that you need to redirect a URI that contains a query string, a separate
map block will be created to map the $request_uri against an re.escaped version of your
alias that contains the ? character. Otherwise, when no query string is present, the
test is made against $uri, which has much more processing done with it (query string
removal, removal of unnecessary '/'s, and so forth).
NGINX configuration
The resulting file (stored in output/$(ALIAS_FILE)) is ready to be included into
your nginx configuration file (in an http stanza). Once the map is created, use the
ALIAS_MAP variable in your processing.
include /opt/web/output/alias_map.txt;

server {
listen *:80 ssl;
server_name example.server;

# Redirection logic
if ( $redirect_uri ) {
return 301 $redirect_uri;
}

location / {
alias /opt/web/output;
}
}

This configuration uses the evil if statement, but it's concise. If you have a better
approach, please create a pull request, and I'll add it to this doc (or replace it if it
makes more sense).
I've chosen to use a 301 redirect here, because I'm confident of the permanency. During
testing, you may want to use a 302.
