drmkit 0.1.1

Fixed

• drmkit-session: libseat's own diagnostics (why a seat could not be opened) now arrive through drmkit-log, tagged [libseat], at error level, as the reference routes them. They went to the log crate at debug level, which drmkit-log does not read. The libseat-log feature no longer does anything beyond libseat, and is kept for 0.1.x.

All 21 crates are on crates.io at 0.1.1. Full diff: v0.1.0...v0.1.1.
