Provide a wp-config-sample.php that enables WP_DEBUG during a wp-cli controlled installation

wp-cli uses the wp-config-sample.php file inside a WordPress directory to setup WordPress and leaves the WP_DEBUG value as it found it. By providing our own wp-config-sample.php, we can control this a bit more.

This setups up a default mu-plugins directory as well that we should then copy to new installations.
Improve the .gitignore file

* Ignore .sql.gz files
* Prepend a slash to paths to make them Vagrant-dir-relative instead of matching anywhere they are found

Introduce custom apc.ini, set apc.shm_size to 128M

Per discussion in issue #68, it makes sense to set APC's memory limit to 128M instead of the default 32M that it ships with. Using a custom apc.ini file makes it easier to further customize other APC settings as we move forward.

Closes #68
Bump default memcached memory allocation to 128M from 64M

Testing large sites can include testing large amounts of cached data. Bumping the memcached limit to 128M is still supported by our server config at the 512M level. We can no customize other memcached settings at will with the linked memcached.conf file.

Closes #70
Happier default URL message than hello world
Include phpinfo at the default IP

It's helpful to have quick access to the PHP config on the server, especially as we consider various changes. This can now be accessed at http://192.168.50.4/phpinfo/ by default.
Separate directory change from status output in DB import script

This line was causing a miss on SQL files that were ready to import on my machine. Breaking it into two lines resolved the current issue. Going to explore why this could have been, but this commit may help others.
