Release v0.5.1

Sets the version and dates the changelog entry for the control-transfer
fix. v0.5.0 shipped a binary whose control transfers stalled, so a
client could not enumerate a device against it — that release should not
remain the installable one.

Verified against the release build, not debug: control transfer returns
the J-Link's real descriptor and the bulk exchange returns its version
string.
