Feed title as separate value from bookmark folder name

[9p6]

Is your feature request related to a problem? Please describe.
I often reuse the same simple folder names like "news" at different places for my livemarks which leads to them having the same title and by consequence difficult to tell apart in preferences list.

Describe the solution you'd like
Keep feed title as separate value:

• do not change feed title on bookmark folder rename
• do not change bookmark folder name on changing feed title

Thank you!
