LLeMbas Desktop 0.7.1, re-released: the fix folded in, no 0.7.2

The first 0.7.1 aborted on Linux before its window appeared (it read
WebKitWebView's write-only 'settings' property). The owner asked for the
patch to be released again rather than followed by a 0.7.2: this commit is
0.7.1 as it should have been, and tag v0.7.1 moves here. The release
workflow now replaces the release of a tag that is pushed again.
