Fixes c1d3bad64f, which crashed with:

It's nicer to use 'irc.channel' instead of 'irc.args[0]', and .channel
provides the actual channel name (stripped of the statusmsg prefix),
so it can be used by plugins when they want to use the actual channel
name.
* supybot-plugin-create: compactify import statements in the template
* supybot-plugin-create: prefer importlib over imp on Python >= 3.4
The imp module is deprecated as of Python 3.4[1], with importlib being the successor. However, importlib is only available in Python 2.7+ and 3.1+, so we should still use a fallback.

* test: add test cases for supybot-plugin-create
* -plugin-create: fix errors when only a subset of args are given
* -plugin-create: rename --real-name to --author/-a
These days, working under a pseudonym or alias is not unheard of, so putting emphasis on real names feels somewhat out of place.
* -plugin-create: add -d as an alias to --desc for consistency
This fixes /names parsing when ! is a prefix character and userhost-in-names is enabled: previously, strings such as "!@user!ident@some.host" were incorrectly split into "" for nick and "@user!ident@some.host" for ident@host.
