Bug 25032: Chomp stringified exception
If we catch a Koha::Exception-derived exception, the log is put in a
single line. If the code 'dies' then a newline character is appended to
the string. This patch chomps it so it displays in a single line.

To test:
1. Tweak Koha::REST::V1::Cities::list in the try block so it dies before
   render
2. Restart plack and try the original test plan
=> FAIL: Notice two lines are logged
3. Apply this patch
4. Repeat 2
=> SUCCESS: Only one line in the logs
5. Verify rendering a Koha::Exception works as well:
   Koha::Exceptions::Exception->throw("Nada!");

Bug 25032: Generic unhandled exception handling on API
This patch adds Koha::Logger as the default logger for the API, and
introduces a new helper plugin that takes care of handling the unhandled
exceptions. Basically, with this we would write something like this in
our controller methods:

    try {
        ...
    }
    catch {
        if ( know_exception ) {
            handle_known_exception($_);
        }

        $c->unhandled_exception($_);
    }

Without this, we end up adding more and more handling 'just in case'.

To test:
1. Edit the Koha/REST/V1/Cities.pm 'list' method adding
   die("Nada"); before the render step.
2. Restart plack and try the endpoint
=> FAIL: A generic error is displayed, and no traces of the original
problem are found on the logs.
3. Apply this patches, make sure your instance's log4perl has the
   introduced lines for API with the right path.
4. Repeat 2
=> SUCCESS: The message is still generic, but you see something is
logged in /var/log/koha/kohadev/api-error.log
5. Change die("Nada"); for a real exception like:

    use Koha::Exceptions;
    Koha::Exceptions::DuplicateObject->throw("Nada");
6. Repeat 2.
=> SUCCESS: The message is generic, but a meaningful text is added to
the logs.
