phpstylist: update to 1.1

[chrstphrchvz (Christopher Chavez)]

The ​upstream project appears to have no activity by its author since the release of phpstylist 1.0 in 2007. Someone made ​phpstylist 1.1, a third-party bufix release, in 2013; see ​announcement. However I found no indication that this third-party release is maintained, either.

If updated, consider addressing #29658.

Alternatively, should this port be deleted? According to ​Repology, MacPorts is the only package manager offering this project. Maybe there is a maintained alternative. (I personally do not use this port.)
