Fixes for cookie import and export (covers 1.1.13 and 1.1.14).

• Plain-text import now works in the manager. Cookie: headers, bare name=value pairs and Set-Cookie lines without Domain= were rejected since 1.1.5; the manager now asks for a domain exactly when the text needs one.
• Clearer error: text that is recognised but carries no domain now says so, instead of claiming the format is unknown.
• HAR files with minimal cookie entries (name and value only, as exported by browsers) are now imported.
• The popup no longer derives cookie domains from internal browser pages such as about:newtab.
• The cookie counter in the popup now follows the active search filter.

The Cookie header export stays a valid HTTP header (a=1; b=2) so it can be pasted straight into curl or the developer tools.

Initial Firefox release of Cookie Brother 1.1.12.
