Valentin Lorentz 833af36b08 all plugins: auto-generate READMEs
Starting with this commit, there should be no "original" text
in READMEs.
Instead, the entire text should be in docstrings, and READMEs
should be automatically generated from these docstrings.

Motivation:

* The same help is available both via IRC and in the README
  (although the README can be more detailed, as only the first
  paragraph will be shown on IRC)
* This will allow auto-generating plugin help on docs.limnoria.net
  using the same content as the README, as it's sourced from the
  docstrings

Additionally, this converts all READMEs from Markdown to ReST,
because the documentation already uses ReST, and other docstrings
in the codebase are in ReST for this reason.

This plugin allows users to define aliases to commands and combinations
of commands (via nesting).
Importing from Alias
^^^^^^^^^^^^^^^^^^^^
Add an aka, Alias, which eases the transitioning to Aka from Alias.
First we will load Alias and Aka::
<jamessan> @load Alias
<bot> jamessan: The operation succeeded.
<jamessan> @load Aka
<bot> jamessan: The operation succeeded.
Then we import the Alias database to Aka in case it exists and unload
Alias::
<jamessan> @importaliasdatabase
<bot> jamessan: The operation succeeded.
<jamessan> @unload Alias
<bot> jamessan: The operation succeeded.
And now we will finally add the Aka ``alias`` itself::
<jamessan> @aka add "alias" "aka $1 $*"
<bot> jamessan: The operation succeeded.
Now you can use Aka as you used Alias before.
Trout
^^^^^
Add an aka, trout, which expects a word as an argument::
<jamessan> @aka add trout "reply action slaps $1 with a large trout"
<bot> jamessan: The operation succeeded.
<jamessan> @trout me
* bot slaps me with a large trout
This ``trout`` aka requires the plugin ``Reply`` to be loaded since it
provides the ``action`` command.
LastFM
^^^^^^
Add an aka, ``lastfm``, which expects a last.fm username and replies with
their most recently played item::
@aka add lastfm "rss [format concat http://ws.audioscrobbler.com/1.0/user/ [format concat [web urlquote $1] /recenttracks.rss]]"
This ``lastfm`` aka requires the following plugins to be loaded: ``RSS``,
``Format`` and ``Web``.
``RSS`` provides ``rss``, ``Format`` provides ``concat`` and ``Web`` provides
``urlquote``.
Note that if the nested commands being aliased hadn't been quoted, then
those commands would have been run immediately, and ``@lastfm`` would always
reply with the same information, the result of those commands.
