Credit the plugin to its actual author, and 1.4.3

The header went out as "Author: WEDSMP" with a Plugin URI of example.com. That
is what wp-admin shows to whoever installs it, which is why it is worth a
release of its own rather than waiting for the next change.

Author is now Kristian Wind, with an Author URI pointing at where the source
lives, and the readme credits kristianwind rather than wedsmp.

ci/static.sh now fails on a placeholder in the header. It catches the generic
markers — example.com, TODO, yourname, an unfilled <...> — and it would have
caught the Plugin URI. It would NOT have caught "WEDSMP": a made-up vendor name
is indistinguishable from a real one to any check, so an empty field is warned
about and a wrong-but-plausible one cannot be.

+= 1.4.3 =
+* The plugin is now credited to Kristian Wind, with a link to where its source lives. It previously carried a placeholder name.
+
 = 1.4.2 =
 * The plugin now has an icon, so it no longer shows up as a generic grey plug under Dashboard → Updates.
 * "Check again" on the updates screen really does check again. It previously reused a cached answer for up to six hours, which made a brand new version look like it had not been published.
