Use gfm-mode instead of gfm-view-mode

[bobrowadam]

I'm not sure if there is something I'm missing in using gfm-view-mode.
but since it makes editing commands (kill-line, delete-char etc.) work in a non expected way
I think we should use gfm-mode instead.

@bobrowadam the view mode is quite important to show smooth headings and markdown rendering.
I did some fixes today morning on eca-emacs, can you try that before?

@ericdallo
OK I see. Can you tell me if you are having issues with kill-visual-line (C-k) delete-char (C-d) kill-word (M-d).
for instance, C-d doesn't work on the first prompt char. M-d doesn't work on the current word and C-k doesn't work at all. maybe it something with my config?.

I can confirm some of those stopped working for me too, but couldn't understand why yet, it might be related with overriding the parent major mode, if you find anything LMK, but overall, the gfm-view-mode is working and improved a lot UI
