questions.yn: Perform string, not identity, comparison against 'y'

The `is` operator performs object identity comparison.  Changing to `==`
implements the expected behavior.

Use the mock library to add tests verifying the API of questions.yn.

Alias: Restore recursion limit and limit memory use

The (faulty) detection of recursive Aliases was removed in
a656fd06930541103c70297825d6f5f5956ecc45, claiming that "our nesting
limit will catch issues now."  However, nested Aliases weren't actually
increasing the nesting level.

Actually increasing the nesting level when an alias is executed restores
the intended behavior.  Additionally, limiting the size of the
expanded arguments to an alias prevents exponential growth of memory
usage for certain malicious inputs/aliases.

release: Remove reference to freshmeat^Wfreecode

freecode.com, nee freshmeat.net, is now a completely static site.  Since
it is no longer allowing updates, no need to worry about pushing
information about Supybot releases to it.

callbacks: Properly handle nested command errors

Using Raise=True was only papering over the real problem in the nested
command error handling.  The actual issue is that we were trying to
return an IrcMsg from NestedCommandsIrcProxy.__init__.  Dropping
Raise=True and moving return to its own line is the correct fix and
resolves the test failure in testMaximumNestingDepth.

Anonymous: Move "say $nick" functionality to new tell command

Allowing Anonymous.say to send a message to either a nick or an
(implicit) channel through the use of first('nick', 'inChannel') changed
the behavior of the command by making it impossible for 'inChannel' to
take effect.

This meant that any previous users of the command that expected "say
some text" to send "some text" to the current channel would instead try
to send "text" to the user "some".  Depending on the value of
conf.plugins.Anonymous.allowPrivateTarget, this would result in either
an error or a strange message to a random user.

Creating a new tell command solves this issue as Anonymous.channel now
goes back to its simple 'inChannel' wrapper.

.travis.yml: enable fast-finish

If I understand correctly, this makes the build fail when one build fails without having to wait for all builds to finish.

This might abort building for those which haven't finished yet, but we probably want to know that build fails as soon as one build fails.
