epiphany 2.26.0 and webkit

[Congac <congacx gmail com>]

Built Epiphany 2.26.0 from source and added  -with-engine=webkit, but still Epiphany uses Gecko.
When I looked at the configure options provided in the source, then webkit does'nt seem to be  mentioned.
Have webkit option been removed from this release or am I missing something?

Also I built 2.27.1 and there webkit worked fine (since its default), but strangely Epiphany could'nt remember any paswords. I was'nt even prompted if I wanted to save password.
