Merge pull request #348 from fleaflicker/master

Jersey module's pom.xml has hard-coded Jackson version, should use ${jackson.version}
Upgrade to tomcat-djbc 7.0.41.
Add %app and %pid patterns for syslog appenders.

When present (including by default) the tokens `%app` and `%pid` will be
replaced with the name of the Dropwizard application and PID of the
process respectively.

This is in line with the convention for many Linux processes to prefix
their log messages with: "ApplicationName[PID]: ".

The PID can only be determined automatically for some UNIX JVMs
(including HotSpot). For others, it will be omitted entirely.

Fix test to work with new AsyncAppender

This is supremely dirty. I'd rather do it differently, but didn't want
to pollute the public API of AsyncAppender to do it.

Make Liquibase migrations file an optional CLI arg

Sometimes it's desirable to maintain/package your database migrations
outside of your application JAR (e.g. when the migrations file is
massive).

Lets add an optional argument to all Liquibase Commands that permits
specifying the path to the migrations file in the local filesystem.

Omitting this option retains the default behaviour.

Note: I'm not entirely sure how best to test Command arguments, so there
are no tests. I used `dropwizard-example` to check that it roughly works
as expected, but that doesn't really qualify as testing.
Remove some unnecessary imports

Clean up AbstractLiquibaseCommand a little.
Leverage Servlet 3's registration API.

This allows us to drop ServletBuilder and FilterBuilder.
