Release v0.021

A breaking change in this release: ysql no longer needs the word query to run a query. With the earlier removal of the write command, the query command was the only way to run a query. Instead of requiring the additional command, now we can save a little bit of typing.

This release has plenty of additions to the ygrok script, allowing it to easily parse logs from Apache HTTPD and Syslog, the output of ls -l and ps. There's also a new -l flag to allow loose matching of input lines.

This release also allows you to add your own ygrok patterns. In addition to adding your own custom patterns, you can list all the existing patterns by doing ygrok --pattern. See the ygrok documentation for more details.

With all the possibilities, ygrok patterns can now be organized into namespaces. This will hopefully make it easier to manage as we add more patterns to the Yertl core.
