The domain has been 'comiceasel' since 2012 while the wordpress.org slug is
'comic-easel'. Language packs from translate.wordpress.org are keyed to the
slug, so they could never load; no working translation ever shipped against
the old domain. Renames the domain in every gettext call, in
load_plugin_textdomain(), in both Text Domain headers, and on the lang/
template files, which already carried comic-easel domain markers internally.
Option keys, admin page slugs, nonce actions and style handles that share the
comiceasel prefix are deliberately left alone; only the $domain argument moved.
